Law Review 2008: Ideas for Student Notes.

Let me know if you use one of these.

Patently-O Bits and Bytes

  • Duplicate fee forms no longer required at the PTO [LINK]
  • As previously announced, PTO fees will be up 5% beginning October 2. Is it worth $50 to get you application in a few days early? [LINK]
  • Admission to Practice before the PTO: Franklin Pierce professor Tom Field recently petitioned the USPTO to loosen its limits on eligibility to practice patent law before the PTO – especially with respect to folks with a background in computer science [LINK]. In addition to Professor Field’s suggestions, I would add that the limitations on those who can practice design patent law are silly. At least any attorney who passes the registration exam should be allowed to practice design patent law.
  • CLE Requirement: Rumors are that the PTO continues to move forward with a proposal mandatory continuing education for registered patent practitioners. I applaud the move – especially if regular reading of Patently-O can count toward the requirement…
  • Foreign Outsourcing: The ABA says foreign outsourcing can be ethical. [LINK]. The new ethics opinion does not address commerce department concerns regarding export restrictions. [Link]

The Clarified Law of Inequitable Conduct

Although not new writing law, in Star Scientific, Chief Judge Michel does a nice job of clearly breaking down inequitable conduct analysis into simple two steps. The case clarifies that threshold levels of materiality and intent must each be proven by clear and convincing evidence.

Inequitable Conduct Two Step Analysis:

  1. Whether the accused infringer proven threshold levels of (a) intent to deceive the PTO and (b) materiality, both with clear and convincing evidence. Although the intent element may be proven by circumstantial evidence. The clear and convincing standard requires that the evidence must be strong enough to point to “intent to deceive” as the “single most reasonable inference able to be drawn from the evidence.”
  2. If both elements are proven by clear and convincing evidence, the court should “look to the equities” to determine whether the evidence warrants a finding of inequitable conduct and thus unenforceability. It is only at this second stage when the court may balance the relative weight of proof. In particular, “[t]he more material the omission or the misrepresentation, the lower the level of intent required to establish inequitable conduct, and vice versa.” (Quoting Critikon, 120 F.3d 1253 (Fed. Cir. 1997)(J. Rich)).

Still unclear is the meaning of “threshold.” Presumably proving a “threshold level of intent” should be easier than simply proving “intent.”


Important Inequitable Conduct Decision: Defendant Must Prove its Case

Star Scientific v. R.J. Reynolds Tobacco (Fed. Cir. 2008)

After a bench trial, the district court held that Star’s tobacco curing patents were unenforceable due to inequitable conduct during prosecution and invalid as indefinite. This post will discuss the inequitable conduct issues.

The Star patents are directed at a method of making healthier tobacco (same nicotine, but fewer nitrites and other chemicals). Higher end organic or green tobacco is perhaps the only growth market in the lagging US market. The inequitable conduct issues in this case revolve primarily around a letter received by the prosecuting attorneys from a Star scientist indicating that Chinese tobacco already had lower levels of nitrites due to “their use of old [radiant heat] flue-curing techniques.” Neither the letter nor a set of similar data were ever disclosed to the PTO.

An accused infringer can defang a patent by showing the patentee guilty of inequitable conduct during prosecution. To successfully prove inequitable conduct, the accused infringer must present “evidence that the applicant (1) made an affirmative misrepresentation of material fact, failed to disclose material information, or submitted false material information, and (2) intended to deceive the [PTO].” An issued patent is presumed valid and enforceable – thus, the “burden of proving inequitable conduct lies with the accused infringer. The patentee need not offer any good faith explanation unless the accused infringer first carried his burden to prove a threshold level of intent to deceive [and materiality] by clear and convincing evidence.” Further, “[e]ven if a threshold level of both materiality and intent to deceive are proven by clear and convincing evidence, the court may still decline to render the patent unenforceable.”

“The need to strictly enforce the burden of proof and elevated standard of proof in the inequitable conduct context is paramount because the penalty for inequitable conduct is so severe, the loss of the entire patent even where every claim clearly meets every requirement of patentability.

. . .

[C]ourts must ensure that an accused infringer asserting inequitable conduct has met his burden on materiality and deceptive intent with clear and convincing evidence before exercising its discretion on whether to render a patent unenforceable.

. . .

If a threshold level of intent to deceive or materiality is not established by clear and convincing evidence, the district court does not have any discretion to exercise and cannot hold the patent unenforceable regardless of the relative equities or how it might balance them.

Specific Intent: As the CAFC held the 1995 Molins case, the intent requirement is “specific intent to . . . mislead[] or deceiv[e] the PTO.”

“Rather, to prevail on the defense, the accused infringer must prove by clear and convincing evidence that the material information was withheld with the specific intent to deceive the PTO.”

When circumstantial evidence is used to prove intent, that evidence “must still be clear and convincing” and intent to deceive the PTO must be “the single most reasonable inference able to be drawn from the evidence.” As a flat rule, information is not material if it is cumulative to that already disclosed.

In this case, prosecution was begun at the Sughrue Mion firm and then moved to the Banner Witcoff firm. RJR’s theory of intent was that the firm switch was necessary to avoid disclosing the letter. Star’s witness stated that the “reasons behind the replacement of the Sughrue firm were that a key partner passed away and that [the witness] observed a Sughrue attorney perform unsatisfactorily in an unrelated prosecution.” The district court, however, rejected that testimony as unbelievable. On appeal, however, the CAFC reversed:

“[E]ven if Star’s explanations are not to be believed, it remained RJR’s burden to prove its allegation regarding the reason for the Sughrue firm’s dismissal. RJR cannot carry its burden simply because Star failed to prove a credible alternative explanation.”

Here, the court found that RJR had simply not proven its case:

“RJR failed to elicit any testimony or submit any other evidence indicating that Star knew what the Burton letter said prior to replacing the Sughrue firm, or that the letter was a reason for changing firms. RJR admitted at oral argument that it failed to even ask [Star’s] executives about these critical facts, and RJR failed to identify any testimony or other evidence when specifically asked by us to do so in supplemental briefing. Further, a review of the record shows that Williams actually testified, in response to a different question, that he had never seen the Burton letter prior to his deposition in the present litigation. This statement was never impeached, questioned, or explored by RJR’s counsel. RJR identified Perito, Star’s chairman, as the officer who made the decision to terminate the Sughrue firm, but Perito was never asked whether he had knowledge of the Burton letter or whether it played any role in his decision to change firms.

In the end, the court concluded, that RJR had simply failed to provide sufficient facts to support an inference of intent to deceive. Reversed and Remanded.


  • The decision gave Star’s stock (STSI) a nice bump:

Of course, there is no “legal” impact, but I query the importance of the fact that both prosecution firms (Sughrue Mion and Banner Witcoff) are well known and well respected in the legal communities.

Greg Aharonian Discussed the WSJ’s “Idiotic Article on Patent Tr-lls”

By Greg Aharonian [LINK]

The 11 August 2008 edition of the Wall Street Journal, page R6, has an idiotic article on patent licensing, starting with a review of the Microsoft v. Avistar squabbles. Microsoft earlier was in talks with Avistar to license its technology, but in the midst of discussions, filed reexam requests challenging 29 Avistar patents, causing Avistar a month later to fire 25% of its workforce (27 employees). Avistar is crying foul, while Microsoft is arguing it found legitimate prior art that the PTO must use to reassess the validity of the patents.

I looked at a few of Avistar’s patents (7412482, 7398296, 7152093 – some of the earlier patents are assigned to Collaboration Properties or Vicor Incorporated). On the side of Avistar, many of their patents cite an excellent amount of patent and non-patent prior art. On the side of Microsoft, the patents are in the crowded area of network communications, so a priori I would not be surprised if a company like Microsoft that can afford to spend tons of money for prior art searching has found additional prior art to use in the reexam requests. Unless the prior art they cited is bogus in order to cause delays to squeeze Avistar, I would say that Microsoft’s countermove is a legitimate tactic.

In short, this is a case that has little to do with tr-lls, but rather is a case that should be the basis for an article on the tactics of prior art searching (how much should small companies spend on searching during patent prosecution versus how much should they spend before entering into negotiations or litigation?). Indeed, if anyone has seen any of the Microsoft reexam requests, I’d be interested in knowing the quality of the new prior art that they found. But the article uses this squabble as an intro into the ill-defined, made up problem or tr-lls (tr-lls being the restless-leg-sydrome of the IP world). The author of the article, not wanting to do much thinking, sets the stage of the article as follows:

At the epicenter of the struggle are so-called ‘patent tr-lls’, a derogatory term for small firms whose only business is to buy patents and assert them in court in hope of obtaining large settlements or damages.

This is a sentence of economic nonsense. First, is ‘tr-ll’ really a derogatory term if tr-lls are using the same tactics as the infamous non-tr-ll tr-ll, IBM? If, when IBM was doing this, it didn’t earn the label of derogatory, it shouldn’t be applied now except as a compliment.

Worse, this paragraph completely betrays free markets (something the Journal is glad to do when it is in the interests of its big company buddies), because it forgets the fact that a patent is an asset created by the government in exchange for an inventor’s public disclosure of a new and useful invention. When the asset is so created, there is absolutely nothing freakin wrong with people doing with patents what they do with all other financial assets – buying, selling and exploiting them. To attack this practice is to attack free market economics. If an inventor doesn’t have enough money to fully enforce his or her patent, it is pure free market economics for that inventor to sell the patent (for a fixed sum and/or royalty) to another economic player who can fully enforce the patent. To complain about this is to attack free markets (something too prevalent in big increasingly-uninnovative companies).

Speaking of which, the article quotes head abuse-patent-reform leader Mark Chandler of Cisco (who I would be glad to debate this issue with, while I am totally drunk, and still win):

Mark Chandler, general counsel of Cisco Systems, says companies that don’t produce anything can buy low-cost patents, hire contigency fee lawyers and file lawsuits seeking massive damages for patents that contribute negligible value to a product. Proposed patent reform that links damages to the economic value of the patent would help solve the problem, he says.

Again, Chandler is attacking free-market economics, in that there is absolutely nothing wrong with companies raising funds to help enforce patents where the original inventor does not have the financial resources to do so. And I don’t think that is what Mark is whining about.

Rather what I think he is whining about is that a) companies like Cisco refuse to spend much time and money monitoring issued patents in their field to anticipate such problems (something the bio-pharma-chem companies, acting like grownups, routinely spend lots of money doing so), and b) companies like Cisco (and most of Silicon Valley) refuse to pool their monies and talents to build prior art resources and tools to help kill much of the crap being issued by the PTO that is used to harass children such as Cisco. I have asked around for 15 years in Silicon Valley for funding to build two prior art collections, one to remain in the Valley for everyone’s use, and the second to be donated to the PTO for examiner’s use. No interest whatsoever, and not just no interest in not funding me (hey, I know I am a jerk), but they don’t want to fund anyone to effectively solve the prior art problem. Because the large companies like Cisco (lead by …. IBM) want to continue to get their crappy patents (which would be threatened by any serious prior art effort – that patent peer review project being a logistic scam at IBM’s behest to prevent serious treament) while whining about smaller companies’ crap.

So anyone use the full word ‘tr-ll’ with the ‘o’ in the patent world is either an idiot or a liar. Or both. No crappy patents should be asserted in courts for only one reason – that such crappy patents don’t issue in the first place. But will companies’ like Cisco use their clout to get Congress to investigate incompetent and corrupt PTO management? NO. Until they do, they should stop whining. If someone gives me his address, I will send Mark a pink blankee he can wipe his tears with.


Patent Law Bits and Bytes No 61

  • Three Bits from the files of Hal Wegner:
    • BPAI Evidence: In a recent petition in Reexamination No. 90/006,707 (2008 Westlaw 2938366), the Commissioner of Patents barred an applicant from submitting a reply brief that contained new evidence. The proffered evidence was a citation to a dictionary definition. This should serve as a reminder to applicants that the evidence for a BPAI appeal should be laid prior to the appeal.
    • Classen v. Biogen: This case has been waiting an appellate decision since oral arguments one year ago. At least one patent is challenged under 35 U.S.C. 101 as it arguably covers the process of “thinking about” an immunization schedule and then immunizing.
    • Great upcoming conference in London, November 11:

Albritton v. Patent Troll Tracker: Patently-O’s Subpoena

I have now received a nonparty subpoena in Eric Albritton’s defamation case against Cisco and the Patent Troll Tracker. The requests are quite broad. Blog commentators may want to check Request Number 2 that could require disclosure of their information. 

2. All DOCUMENTS REFERRING or RELATING to comments, emails, COMMUNICATIONS or responses to THE BLOGS regarding (1) the integrity, reputation or ability of ERIC M. ALBRITTON; (2) the filing of Civil Action No. 5:07-CV-00156, styled ESN, LLC v. Cisco Systems, Inc., in the United States District Court for the Eastern District of Texas; or (3) the October 16-17, 2007 postings on [File Attachment: albrittonsubpoena.pdf (109 KB)]

In part, this request is seeking information about the identity of anonymous blog commentators and those who have sent me private emails regarding this case. As I have mentioned previously, my blogging service retains additional information regarding the identity of commentators (such as IP address, etc.), and a full response to the subpoena request could include that information. In a letter to Albritton’s attorney, I objected to the subpoena requests for several reasons including the following specific objection to Request Number 2:

Request Number 2 asks about comments on THE BLOGS. Comments are posted on Patently-O and are publicly available at no charge to you. Because these comments are already available online, this request is likewise unduly burdensome and overbroad. Furthermore, most commentators post anonymously with a strong expectation of privacy in their identity. Similarly, I often receive communications sent under the condition and/or expectation of privacy and anonymity. This happens with any reporter – but is especially common in law and politics where we often find negative retribution for speaking out. I strongly support this right of anonymity and do not plan to reveal particular information that could lead to the identity of those sources without a specific court order on the topic. As the Supreme Court recently held, “Anonymity is a shield from the tyranny of the majority. . . . It thus exemplifies the purpose behind the Bill of Rights, and of the First Amendment in particular: to protect unpopular individuals from retaliation . . . at the hand of an intolerant society.” McIntyre v. Ohio Elections Comm’n, 514 U.S. 334, 357 (1995). Eighth Circuit law supports this ideal – especially as regard to reporters and their sources. In Continental Cablevision, Inc. v. Storer Broadcasting Co., 583 F. Supp. 427, 435 (E.D. Mo. 1984), for instance, the district court held that “news reporters enjoy a qualified privilege, derived from the first amendment guarantee of a free press, to withhold from discovery in a civil case confidential or non-confidential sources, materials, or other information where such discovery would impinge on the ability of the media to gather and disseminate news. Said privilege may be defeated in a particular case where the party seeking discovery can demonstrate that the testimony, material or information sought is relevant enough, and otherwise unavailable, to outweigh the first amendment interest of the media. A balancing analysis is the benchmark.” You have provided no such balancing.

Time will tell whether a motion to quash will be necessary.

Public & Experimental Use: Reduction to Practice Requires Knowledge that Invention Works for Intended Purpose

In re Omeprazole Patent Litigation (Fed. Cir. 2008)

The CAFC has affirmed a lower court trial finding that AstraZeneca’s Prilosec (omeprazole with an enteric coating and a subcoating) patents are infringed by the ANDA filings of Apotex, Torpharm, and Impax. (See U.S. Patent Nos. 4,786,505 and 4,853,230). This complex consolidated case has been handled by Judge Jones of the Southern District of New York. The case includes several important procedural issues, but here I focus on public use.

Public Use of a Pharmaceutical Formulation: Under 35 U.S.C. § 102(b), a patent will be considered invalid if the invention was “in public use” more than one year before the filing date. (i.e., before the “critical date”). The use in question was Astra’s large clinical trials used to test its omeprazole formulation. The district court ruled for Astra on two separate grounds: First that the clinical trials were an “experimental use” and therefore cannot qualify as public uses and second that the formulation was not yet ready for patenting until after the trials were completed.

Experimental Use and Reduction to Practice: In a series of cases over the past decade, the Federal Circuit has made clear that the experimental use defense “cannot negate a public use” that occurs after the invention is reduced to practice. At the same time, public use now requires proof that an invention is “ready for patenting” which generally requires reduction to practice (or at least being enabled to practice). For the most part, this rather new interpretation of public use subsumes the experimental use defense.

Here, the pills had been manufactured and were being used by clinical subjects. However, there were not “reduced to practice” because RTP requires knowledge “that the invention would work for its intended purpose.” On appeal, the Federal Circuit refused to overturn the lower court’s factual findings – instead agreeing the formulation was not reduced to practice because the company lacked experience of how it would perform clinically:

[Astra’s expert witness] testified that as of May 1983 the Astra scientists did not have enough information to satisfy themselves that the Phase III formulation would work for its intended purpose. Instead, he testified that the Astra scientists thought the Phase III formulation “had a good possibility to be used as a marketing drug” but that the team did not have long-term stability data and had “no experience of how it performed in clinical studies.”


The Astra scientists had long understood that omeprazole could provide a safe and effective treatment for certain gastrointestinal diseases. The challenge they faced was developing a formulation to deliver omeprazole to the small intestine, a challenge that was made difficult by omeprazole’s sensitivity to acidic environments, such as the stomach. Impax has not demonstrated that, without conducting the Phase III clinical tests, the inventors knew that the Phase III formulation would achieve the goals of long-term stability and in vivo stability such that it would be effective as a treatment for gastrointestinal disease.

Because the efficacy of the formulation was not reduced to practice, its use could not be a public use.


  • Of interest here is the idea that reduction to practice requires knowledge that the invention will work for its “intended purposes.” The specification of these patents detail the need for stability, so that purpose is clear. Because “purposes of the invention” have been used to limit claim scope, many modern patent applications don’t include such information. In those cases, will the purpose be found in extrinsic evidence?
  • The court here focused on reduction to practice to fulfill the “ready for patenting” prong of the public use analysis. Seemingly, the defendants may have had a better shot trying to show ready for patenting based on evidence that “prior to the critical date the inventor had prepared drawings or other descriptions of the invention that were sufficiently specific to enable a person skilled in the art to practice the invention.”

The Surprising Efficacy of Inter Partes Reexaminations

An Analysis of the Factors Responsible For Its 73% Patent Kill Rate And How To Properly Defend Against It

     By Andrew S. Baluch and Stephen B. Maebius, Foley & Lardner LLP[i]< ?xml:namespace prefix ="" o />


In creating inter partes reexamination, Congress hoped to provide a faster, cheaper alternative for resolving questions of patent validity in the U.S. Patent & Trademark Office (USPTO) rather than in the courts.  As a measure of the procedure’s growing popularity and availability, the rate of requests for inter partes reexamination has steadily increased each year, totaling over 308 since the procedure was created in November 1999.[ii]  But, while the pace of reexam requests continues to increase, the end results of completed proceedings have received relatively little attention.

Here, we report the outcomes of all inter partes reexaminations completed as of August 2008.  Surprisingly, the proceedings displayed a high 73% “kill” rate (complete elimination of all claims targeted by the requesters) — a rate which is far above that in litigation (33%)[iii] and ex parte reexamination (12%)[iv]. 

Is the high kill rate explained by the fact that especially weak patents were targeted?  Did the patent owners simply give up because the patents were commercially unimportant?  Or is inter partes reexamination truly the best procedure for a party to use in the U.S. to invalidate a patent? 

For both requesters and patent owners, the present study highlights the factors and strategies favoring success in inter partes reexaminations.  Although the reported statistics appear to favor requesters, a patent owner has unique procedural tools at its disposal both in the courts and at the USPTO.


·         Requester’s Success Rate:  Third-party requesters succeeded in having all claims cancelled or disclaimed in 73% (22) of the first 30 completed inter partes proceedings in which a certificate issued.  These early certificates are likely skewed in favor of quick dispositions in which the patent owner simply failed to respond to a first Office action, which occurred in 43% (13) of the proceedings.  However, when the patent owner did respond to the first Office action, the requester’s success rate fell to 53% (9 out of 17).  In any event, the requester’s likelihood of a complete victory in inter partes reexams is substantially greater than that in ex parte cases during the same period: only 12% of all ex parte reexams since January 2000 resulted in all claims being cancelled.[v]

·         Pendency:  The inter partes proceedings had an average pendency (measured from request date to certificate issue date) of 33.3 months.  Like the requester’s success rate, the overall pendency is skewed by the numerous early cases in which the patent owner simply failed to defend its patent.  Eliminating these uncontested cases dramatically increases the average pendency up to 42.5 months.

·         Grounds of Rejection:  In a first Office action, obviousness was the sole ground of rejection in only 20% (6) of the proceedings, whereas anticipation was a ground of rejection in 73% (22) of the proceedings.  Nevertheless, obviousness-only rejections did not improve the patent owner’s chances of success: 83% (5 out of 6 obviousness-only cases) resulted in all claims being cancelled or disclaimed.

·         No Board Decisions:  None of the first 30 inter partes reexamination certificates was the product of a Board decision.  Only one party, a patent owner, filed a notice of appeal, but then dropped the appeal by declining to file an appeal brief.  In all cases where examiners found claims to be patentable, the third-party requesters did not bother to appeal the finding.

·         Litigation:  Five (17%) of the 30 inter partes reexaminations involved concurrent litigation between the patent owner and third-party requester.  The causes of action were split:  2 declaratory judgment (DJ) actions brought by the third-party requester, and 3 infringement suits brought by the patent owner.  The only still-pending cases involve reexaminations favoring the plaintiff:  one DJ action in which all reexamined claims were cancelled, and one infringement suit in which all reexamined claims were confirmed.

Public Interest in Patent Law Declining: The graph below shows the relative frequency of Google searches for Patent Law.

Nintendo Wii: I was planning to buy the Wii as soon as it reaches Columbia Missouri . . . Now the company Hillcrest Labs has filed both an ITC complaint and a federal patent case requesting that the commission institute a Section 337 investigation of the Wii and its “three-dimensional pointing devices.” The complaints allege infringement of four Hillcrest patents: U.S. Patent Nos. 7,139,983, 7,158,118, 7,262,760, and 7,414,611. The patents include several broad claims directed toward pointing devices that use internal accelerometers to track movements (and the lack of movement) and have a priority date of sometime in 2004. The ‘611 patent issued on August 19, 2008 and the claims appear directed at capturing the Wii.

Damages Tally Begin as Soon as Defendant is Given Notice of Infringement

DSW Shoe Warehouse v. Shoe Pavilion (Fed. Cir. 2008)

DSW holds a utility patent and a design patent on a shoe display system. In 2006, DSW notified off-brand competitor Shoe Pavilion that its displays were infringing. Wanting to avoid trouble, Shoe Pavilion took immediate action and removed the infringing displays. (Although immediately begun, the whole take-down process took seven months.) DSW was not satisfied that the replacement design avoided infringement and subsequently sued.

Damages and Notice: The case raises several issues, but here I will focus on damages. On summary judgment, the district court held that Shoe Pavilion owed no damages for infringement by the initial design because the defendant took immediate action to stop infringing. On appeal, the CAFC vacated that opinion.

The Patent Marking Statute limits damages that may be recovered by a patentee.

In the event of failure so to mark, no damages shall be recovered by the patentee in any action for infringement, except on proof that the infringer was notified of the infringement and continued to infringe thereafter, in which event damages may be recovered only for infringement occurring after such notice. 35 U.S.C. §287(a).

The Pre-1952 Patent Statute included a similar restriction on damages. That statute was interpreted by the Supreme Court in Wine Railway (1936). There, the court held that the recovery by patentee who failed to mark products covered by the patent would be limited to damages incurred after actual notice was provided to the infringer.

The policy behind this approach is to give some level of protection to innocent infringers. However, damages begin to accrue as soon as notice is given. Thus, in this case, Shoe Pavilion is liable for the damages that occurred during the seven-month take down process.

“Without a doubt, the law offers an infringer no exception to liability for the time it takes to terminate infringing activities, no matter how expeditious and reasonable its efforts.”

Vacated and remanded.


  • The court also vacated based on an error of claim construction – finding that the claimed “track and roller” was not limited by the preferred embodiment found in the specification.

Marking of Prescription Drug Does Not Create DJ Jurisdiction for Generic Competitor

PatentLawPic392Prasco LLC v Medicis Pharmaceutical Corp. and Imaginative Research (Fed. Cir. 2008)

Imaginative Research owns of several patents covering a prescription strength benzoyl peroxide wash. Medicis is the exclusive licensee and sells the product under the brand name TRIAZ.  The patents are listed on the box.

Prasco makes a generic version (OSCION) and allegedly competes directly with TRIAZ.

Wanting to avoid the cloud of potential infringement, Prasco filed a declaratory judgment lawsuit against the patentee and licensee alleging non-infringement of the listed patents. The case was dismissed for lack of declaratory judgment jurisdiction, Prasco appealed.

Prasco admits that the DJ defendants did not know about the generic competition until it received the complaint. However, Prasco argued that Article III jurisdiction exists because the defendants (1) listed its patents on a directly competitive product and (2) Medicis had previously sued Prasco (for infringement of a different patent by a different product).  The defendants also refused to sign a covenant not to sue.

Cases or Controversies: Article III of the Constitution limits the reach of federal judicial power to the adjudication of “cases” or “controversies.”  This requirement has been interpreted to encompass only disputes that are “definite and concrete, touching the legal relations of parties having adverse legal interests,” “real and substantial,” and “admi[t] of specific relief through a decree of a conclusive character, as distinguished from an opinion advising what the law would be upon a hypothetical state of facts.”

In MedImmune, the Supreme Court rejected the CAFC’s original test for DJ Jurisdiction that required a “reasonable apprehension” of immanent litigation and replaced it with an amorphous requirement of a “substantial controversy . . . of sufficient immediacy.”

On appeal, the CAFC affirmed that Prasco’s controversy is not sufficient to be justiciable.

Although MedImmune clarified that an injury-in-fact sufficient to create an actual controversy can exist even when there is no apprehension of suit, it did not change the bedrock rule that a case or controversy must be based on a real and immediate injury or threat of future injury that is caused by the defendants—an objective standard that cannot be met by a purely subjective or speculative fear of future harm.

The court further held that DJ jurisdiction does not exist “without some affirmative act by the patentee.”

Regarding marking, the court found that the marking of “products with the applicable patents provides little, if any evidence that [the patentee] will ever enforce its patents.”

CAFC Finally Affirms a Finding of Infringement by Equivalents

PatentLawPic391Dr. Voda v. Cordis Corp. (Fed. Cir. 2008)

Dr. Voda’s case is an exciting tale of an individual inventor litigating against a major corporation in the red sandy soil of western Oklahoma. 

A jury found that Cordis catheters infringed Voda’s patents and adjudged a reasonable royalty to be 7.5% of gross sales. The jury also found the infringement willful and the patents not invalid.  The district court then affirmed the jury verdict but denied Voda’s request for injunctive relief.

Claim Construction: Voda’s claim included the requirement that the catheter be engaged “along a line” of the aorta. The district court, however, found that the claim is not limited to linear portions of the aorta. On appeal, the CAFC confirmed the construction — reminding us that “the context in which a term is used in the asserted claim can be highly instructive.” Phillips. When engaged, it is clear that the catheter may curve along the aorta.

The specification does indicate that the “present invention [includes a] straight portion.” However, the CAFC refused to see that statement as a “clear disavowal of claim scope” because the specification discusses other instances where the same portion could be curved.

Doctrine of Equivalents: Cordis had redesigned some of its products to avoid literal infringement. However, these were found to infringe under the Doctrine of Equivalents. In particular, a “second straight portion” claim element was not literally found in the Cordis products, but the jury found that the products did include an equivalent element.

At the court’s option, either of two tests of equivalent may be used:

Under the insubstantial differences test, “[a]n element in the accused device is equivalent to a claim limitation if the only differences between the two are insubstantial.” Honeywell Int’l Inc. v. Hamilton Sundstrand Corp., 370 F.3d 1131, 1139 (Fed. Cir 2004). Alternatively, under the function-way-result test, an element in the accused device is equivalent to a claim limitation if it “performs substantially the same function in substantially the same way to obtain substantially the same result.” Schoell v. Regal Marine Indus., Inc., 247 F.3d 1202, 1209-10 (Fed. Cir. 2001).

The CAFC looked to Voda’s experts to find evidence of insubstantial difference. In particular, Voda’s expert testified that the Cordis “curve portion” was essentially straight and that “cardiologists would have difficulty distinguishing the two during use.”  In addition, Voda introduced evidence that the Cordis curve portion “performed the same function as a straight portion, in the same way, to achieve the same result. . . . Accordingly, we affirm the jury’s findings of infringement with respect to these claims.”


  • EBay: Voda argued for an injunction based on the irreparable harm to its exclusive licensee. The CAFC rejected that justification — finding that the irreparably harmed must be the party seeking the injunction.
  • Seagate: The CAFC vacated the willfulness finding that was based on pre-Seagate law.
  • Festo: The CAFC did find that some of Voda’s claims were not infringed under the DOA. Those claims had been narrowed during prosecution and were subject to prosecution history estoppel.
  • Prior Appeal: In the 2007 appeal in this case, the CAFC held that Voda could not assert its foreign patents covering the same product in US courts. [LINK]


Reissue Claim is Improperly Broadened if “Broader in Any Respect.”

Brady Construction Innovations v. Perfect Wall (Fed. Cir. 2008) (Non Precedential).

This case is simple. Brady filed for a reissue more than two years after the patent issued. The reissue broadened the claims. Those claims are therefore invalid.

Brady’s original patent issued July of 1992. After losing an infringement action in 2003, Brady filed for a reissue patent. The reissue patent issued as RE39,462 in 2007 and Brady again filed suit. The patentee’s press release at the time tells the story:

“Previously, the Court of Appeals had limited the original slotted track patent in a way that Brady never intended. This new patent removes the limitation recently imposed by the Court of Appeals. From this date forward, anyone who manufactures and sells [any style of] slotted track will infringe Brady’s new patent regardless of how the slotted track is installed.”

35 U.S.C. 251 spells out the guidelines for reissue patent applications. Generally, a reissue is available to correct an error made by the patentee. Although the statute specifically allows a reissue to correct an error in “claiming more or less than he had a right to claim in the patent,” the statute also places a strict two-year time limit on enlarging the scope of any claims.

“No reissued patent shall be granted enlarging the scope of the claims of the original patent unless applied for within two years from the grant of the original patent.”

Any enlargement in scope of any claim element will generally run afoul of the limitation. In particular, the CAFC has repeatedly held that a claim will be considered to be enlarged under Section 251 if “it contains within its scope any conceivable apparatus or process which would not have infringed the original patent. A reissue claim that is broader in any respect is considered to be broader than the original claims even though it may be narrower in other respects.”

Here, based on the construction of the original patent by the CAFC, it was clear that the new claim had been broadened – rendering it invalid.

Todd Dickinson To Take AIPLA Helm

The AIPLA recently announced that Q. Todd Dickinson will become the new Executive Director of the organization. Dickinson is widely considered the most popular PTO director in recent history. Dickinson is also an Obama supporter and would be a likely return-appointee as PTO director if the democratic contender is elected. After leaving the PTO, Dickinson took the job of chief IP counsel for GE after working as a partner at Howry LLP. Dickinson is also known for his ability to bring parties together for compromise solutions – that may bode well for patent reform issues that have begun to divide both the AIPLA and the IPO. Michael Kirk, who has successfully led the AIPLA for more than a decade, is retiring.

Albritton v. Patent Troll Tracker

Thomas Claburn in InformationWeek recently published an article about the defamation cases by Eastern District of Texas attorney Eric Albritton against Rick Frenkel in his role as the Patent Troll Tracker, Cisco, and others. [Patently-O Discussion of the Case]. According to the article, Albritton has now subpoenaed Google – requesting its help uncovering facts.

The subpoena demands, inter alia, that Google turn over ‘all documents referring or relating to communications to or from (1) Richard Frenkel a/k/a/ “The TrollTraker,” (2) Dennis Crouch, individually and sub.nom. “Patently O,” … (7) the blogs [defined as Patently-O and PatentTrollTracker blogs]” regarding Albritton, the filing of the ESN lawsuit, or related TrollTracker postings.’ The subpoena also requests related Google search records (“all documents referring or relating to user searches of the internet and/or the blogs regarding (1) Eric M. Albritton…”) and other records (“all documents referring or relating to the establishment, creation, maintenance, and financial support for the blogs”).

Open Source License Conditions Enforceable Through Copyright Law

Jacobson v. Katzer (Fed. Cir. 2008)

In an interesting decision, the CAFC held that open source license conditions are enforceable under the copyright laws. Jacobson’s open source license at issue here allowed anyone to use his software so long as his conditions are met (such as making any modified code freely available).

Copyright vs Contract: The district court held that violation of the open source conditions are remedied through a contract claim rather than copyright. The CAFC sided with the copyright holder – holding that “Copyright holders who engage in open source licensing have the right to control the modification and distribution of copyrighted material.”

Copyright holders who engage in open source licensing have the right to control the modification and distribution of copyrighted material. As the Second Circuit explained in Gilliam v. ABC, 538 F.2d 14, 21 (2d Cir. 1976), the “unauthorized editing of the underlying work, if proven, would constitute an infringement of the copyright in that work similar to any other use of a work that exceeded the license granted by the proprietor of the copyright.” Copyright licenses are designed to support the right to exclude; money damages alone do not support or enforce that right. The choice to exact consideration in the form of compliance with the open source requirements of disclosure and explanation of changes, rather than as a dollar-denominated fee, is entitled to no less legal recognition. Indeed, because a calculation of damages is inherently speculative, these types of license restrictions might well be rendered meaningless absent the ability to enforce through injunctive relief.

. . . .

The clear language of the Artistic License creates conditions to protect the economic rights at issue in the granting of a public license. These conditions govern the rights to modify and distribute the computer programs and files included in the downloadable software package. The attribution and modification transparency requirements directly serve to drive traffic to the open source incubation page and to inform downstream users of the project, which is a significant economic goal of the copyright holder that the law will enforce. Through this controlled spread of information, the copyright holder gains creative collaborators to the open source project; by requiring that changes made by downstream users be visible to the copyright holder and others, the copyright holder learns about the uses for his software and gains others’ knowledge that can be used to advance future software releases.

This decision is based on the court’s interpretation of 9th Circuit law. However, its impact on patent law may be a reminder that the court will allow patent infringement actions even when the infringement is based on violation of an intricate or exotic licensing contract.
