Over the past two weeks, my family’s thoughts and prayers have been going out to the people of New Orleans. I have many relatives in Mississippi and Alabama, but they are lucky to live far enough north to have avoided the brunt of the storm. There are a number of ways to help those who were not so fortunate. One easy action is send a check to a relief organization. My firm, MBHB is matching employee donations and will be sending a chunk of funds to the McCormick Tribune Foundation here in Chicago.
The AIPLA has set up an assistance page to help in the recovery effort. So far, a number of law firms (both large and small) have offered to give free office space, assistance in brief filing, and free tuition to law school for displaced IP attorneys and law students. Lets hope this spirit of generosity continues.
The ABA also has set up Hurricane Katrina Disaster Relief pages for the attorneys, law offices, and many others needing legal assistance who have been caught in the catastrophic effects of Hurricane Katrina. [see Patent Baristas].
Network Commerce sued Microsoft for infringement of its e-commerce patent relating to the purchase of downloadable electronic content. The district court awarded summary judgment to Microsoft, finding that the company did not infringe either literally or under the doctrine of equivalents (DOE).
Specifically, the lower court found that Network Commerce’s extension of the patent to include Microsoft’s metafile downloads would vitiate the claim requirement that the download an executable file or program.
On appeal, the CAFC did not reach the vitiation requirement. Rather, the appellate panel found that even the basic requirements of element-by-element equivalents had not been sufficiently shown by the plaintiff because the expert declaration did not provide sufficiently specific testimony to prove a limitation-by-limitation analysis.
The expert declaration and other evidence relied on by Network Commerce supporting infringement by equivalents are generalized and do not provide particularized testimony and linking argument on a limitation-by-limitation basis. For this reason the evidence did not raise a genuine issue of material fact. Summary judgment of non-infringement under the doctrine of equivalents regarding metafiles was therefore proper.
Crater holds a patent on a coupling device that operates underwater. In a suit involving trade secret violations, the district court determined that the Government’s assertion of “Military and State Secret privilege” made it impossible for Crater to engage in discovery or to make out a prima facie case. The court therefore dismissed the claims.
On appeal, the CAFC found that the lower court correctly sustained the government’s assertion of the state secret privilege, but erred in dismissing the case.
For the state secret privilege to be properly asserted, “the head of the pertinent government department must formally invoke the privilege on behalf of the government. Then, after reviewing the declarations of government officials and the circumstances surrounding invocation of the privilege, the court must determine whether assertion of the privilege is appropriate.”
After reviewing confidential documents submitted by the Government, the CAFC concluded that the Government had claimed a legitimate state secret. Although the appellate panel recognized that proper resolution of the issues would be difficult in light of the state secret restriction on discovery, the court ordered that the facts of Crater’s claims must be further developed before making a determination of whether those claims should be dismissed.
In dissent, Judge Newman argued Crater should be given access to the Government documents and that the case should proceed in camera.
This case does not raise the constitutional debate about public trials; this is a commercial dispute, of interest only to the parties. It seems clear that the court’s requested remand cannot be implemented without risk of violating the secrecy order, with possible penalty. This is the third judicial cycle of this simple dispute. We should remand this case for in camera proceedings that would protect the information from public disclosure, and allow this dispute to come to closure. Trials in camera of issues subject to secrecy restraints are not new, and such trial would be the appropriate procedure in this case.
Noted attorney and author Hal Wegner has released his first review of IP cases for the October 2005 term of the Supreme Court. Of the seven cases reviewed, two are awaiting oral argument (Unitherm and Illinois Tool); four are awaiting a certiorari decision (Schering-Plough, KSR, Lab. Corp. and eBay); and one is still before the CAFC (RIM v. NTP).
1) Unitherm v. Swift Eckrich: Appellate procedure question of when a court of appeals may overturn a civil jury verdict. Argument scheduled for November 2, 2005.
2) Illinois Tool Works v. Independent Ink:Question of whether a patent creates a rebuttable presumption of market power in a Sherman Act tying case. Argument scheduled for November 29, 2005.
3) FTC v. Schering-Plough: Whether pioneer-generic settlement duopoly settlement agreements are permissible when agreement falls within the scope of the patent. On petition for cert. Odds of being heard are good.
4) KSR v. Teleflex: Whether teaching-suggestion-motivation test for obviousness should be changed. On petition for cert. Odds of being heard are OK.
5) Lab. Corp. v. Metabolite: Whether a medical diagnosis method patent is invalid as non-patentable subject matter under Diamond v. Diehr, 450 U.S. 175, 185 (1981). On petition for cert. Odds of being heard are low.
6) eBay v. MercExchange: Whether the current de facto rule of an injunction always resulting from a finding of infringement and validity should be changed. On petition for cert. Odds of being heard are low — although this is a volatile issue.
7) NTP v. Research in Motion: Extraterritorial reach of U.S. patent law. Last fall, the court denied Pellegrini’s petition for certiorari in a somewhat similar case. These issues will be heard by the Court in some case within the next two years.
Arizona Cartridge Remanufacturers Assn. v. Lexmark Int’l. (9th Cir. 2005).
ACRA sued Lexmark for unfair business practices based on Lexmark’s “prebate” program that allows customers to receive $30 off the price of a printer cartridge if they agree to return the empty cartridge to Lexmark — rather than allowing a third-party remanufacturer to refill the cartridge. ACRA argued that this practice was a restriction on alienability that should be barred.
The district court granted summary judgment in Lexmark’s favor, finding that the restriction on further use was a valid agreement and that Lexmark’s statements about the pricing were accurate.
On appeal, the 9th Circuit found that the post-sale restriction was allowable because the product was patented. (citing Monsanto v. McFarling). Post sale conditions are generally allowed if the good is “reasonably within the patent grant.” The EFF filed a brief in the case that was largely ignored.
DDC Commentary:
For me, the interesting part of this opinion is that restrictions on alienation (resale/repair) of consumer goods are generally not enforceable unless the good in question is patented.
In the wake of this and other cases, pundits are predicting that we will be seeing more “shrink-wrap” licenses restricting repair and modification attached to products that might need repair or modification.
If you plan to take such an action, be sure that your product is patented. (Query — will a design patent be sufficient?)
Andrx sued Elan for antitrust violations based on Elan’s enforcement of its patent and settlement agreement. The district court dismissed the case on the pleadings, finding that (i) Noerr-Pennington immunized Elan for its patent infringement litigation and (ii) Elan’s settlement agreements did not support an antitrust action.
On appeal, the Eleventh Circuit affirmed in part and reversed in part.
Noerr-Pennington: The appellate panel agreed that Noerr-Pennington“shields a defendant from antitrust liability for resorting to litigation to obtain from a court an anticompetitive outcome.” The primary exception to the doctrine arises when the litigation is a “sham.” In this case, it was clear that the litigation was “objectively baseless” and thus did not fall within the exception. (Elan had won a CAFC appeal).
Settlement Agreements: Andrx asserted that settlement agreements signed by Elan to terminate patent litigation were anticompetitive. Under the recent case of Schering-Plough v. FTC, the three elements are required to prevail on a Section 1 Sherman Act action: “(1) the scope of the exclusionary potential of the patent; (2) the extent to which the agreements exceed that scope; and (3) the resulting anticompetitive effects” in the relevant market.
The appellate panel found that Andrx should at least pass the pleading stage because the complaint demonstrated that (1) the patent was necessary for the sale of controlled release naproxen; (2) the license agreement was structured to “effectively bar any generic competitors from entering the market;” and (3) if true, this dynamic would have an anticompetitive effect on the market.
Under Section 2 of the Sherman Act, the Panel found that Andrx had properly alleged specific intent to monopolize and preserve a monopoly in the controlled release naproxen market. That pleading, according to the court, was sufficient to overcome a 12(b)(6) motion.
Link: The Supreme Court has been petitioned to hear the Schering-Plough case. If that hearing comes about, Andrx v. Elan may see a new appeal.
A new flurry of appeal briefs further complicates this closely watched case involving the fundamental question of how the U.S. patent laws can be asserted against foreign activities. Canada based Research-in-Motion (RIM) was at the losing-end of a 2003 patent infringement trial that resulted in a permanent injunction against its popular BlackBerry system. That judgment is stayed pending a series of appeals that have included two appellate court opinions. Now, RIM is asking the Court of Appeals for the Federal Circuit (CAFC) to hear the appeal as an en banc panel of all twelve judges.
Background
In August, 2005, the CAFC released a second appellate opinion in the case. The new opinion focused on the extent that a patent must be practiced within the U.S. to fall under the guise of § 271 of the Patent Act and specifically highlighted on the difference between system claims and method claims with relation to international activities. A system, the court held, is used “within the United States” so long as the United States “is the place at which the system as a whole is put into service, i.e., the place where control of the system is exercised and beneficial use of the system obtained.”A method, however, is only used “within the United States” if “each of the steps is performed within this country.”
As such, RIM (RIMM) was able to avoid infringement of NTP’s method claims but not the system claims because “RIM’s customers located within the United States controlled the transmission of information and benefited from the resulting exchange of information.”
The court also opined on the inapplicability of other portions of 271 to method claims:
Sale: The CAFC found it unlikely that a method claim could infringe through the sale provision of 271(a).
Component: Distinguishing Eolas, the CAFC implied that a method claim would rarely if ever trigger 271(f).
Section 271(g): The import provision only applies to physical articles — and thus cannot be used to find infringement of a method for transmitting information (as claimed by NTP).
Rehearing en Banc
In the wake of the revised appellate opinion, RIM has renewed its request for an en banc rehearing – hoping that a full panel of appellate judges will eliminate the “control and beneficial use” standard for transnational infringement.NTP opposes the rehearing.
RIM’s Petition for Rehearing
In its brief, RIM questioned the panel decision that “use” of a “patented invention” occur can “within the United States” under 35 U.S.C. 271(a) even if significant components or acts specified by the claims are outside the United States. RIM further argued that the panel’s distinction between method and system claims was not given any justification and is “untenable.”
The Panel erred on multiple grounds. First, the Panel fails to follow the plain statutory language extraterritorially limiting § 271(a) liability to “uses . . . within the United States.” As a result, the Panel makes an unsupported distinction between method claims and system claims creating a generic rule for all system claims that fails to consider the nature of the actual patented invention. Second, the Panel ignores basic cannons of statutory construction that forbid extending the patent statute extraterritorially absent clear Congressional direction. Third, the Panel erroneously finds § 271(a) liability based on Decca, a case decided under 28 U.S.C. 1498, the statutory language and purpose of which are entirely different from § 271(a). Fourth, the Panel misapplied that analysis and decided fact issues that should be left for the jury.
NTP’s Opposition to the Rehearing
In its opposition brief, NTP continues its barrage on RIM for its “attempts to delay purely for delay purposes.”
The Panel properly focused on the only pertinent activities for the 271(a) question presented: the acts of millions of U.S.-located BlackBerry users that put into service their U.S.-located BlackBerry handhelds to send and receive wireless emails millions of times each day using U.S.-located transceivers and US.-located email systems equipped with thousands of U.S.-located email gateway redirectors sold by RIM. The only pertinent RIM activities are those establishing inducement and contributory liability – activities conceded by RIM on appeal. Other acts that RIM raises are irrelevant. Indeed, under RIM’S reasoning, use by BlackBerry customers in other countries negates the tort of infringement arising from use in the United States. Such analysis lacks any basis in law, precedent, or reason.
NTP argued that the longstanding principles of the Decca case clearly guide this case, and that “unless [the CAFC] sua sponte intends to overturn Decca and Decca II in a manner that the Supreme Court and Congress have refused, RIM presents no issue that warrants further review.”
Microsoft’s Amicus Brief in Support of the Petition
Microsoft took time to point-out the inconsistencies between the NTP decision and the handful of other recent cases involving extraterritorial application of U.S. patent laws, and the software giant asked the court to rehear this case in conjunction with its own pending AT&T v. Microsoft to ensure a “uniform and consistent body of case law concerning the territorial reach of 35 U.S.C. § 271.”
NTP v. Research in Motion, (271(f) “component” does not apply to method claims).
AT&T v. Microsoft, 414 F.3d 1366 (Fed. Cir. Jul. 13,2005) (271(f) “component” applies to method claims and software being sold abroad);
Eolas v. Microsoft, 399 F.3d 1325 (Fed. Cir. Mar. 2,2005) (271(f) “component” applies to method claims);
Pellegrini v. Analog Devices, 375 F.3d 1113 (Fed. Cir. 2004) (271(f) “component” does not cover export of plans/instructions of patented item to be manufactured abroad);
Bayer v. Housey Pharms, 340 F.3d 1367 (Fed. Cir. 2003) (271(g) “component” does not apply to importation of ‘intangible information’).
Regarding policy, Microsoft argued that limiting 271(a) U.S. patent law to not include any foreign actions, would create “an incentive for American companies to locate certain aspects of their systems outside the United States, primarily to avoid infringement liability. Such an outcome would likely result in loss of jobs, skilled workers, capital, and information technology, abroad.” On the other hand, Microsoft argued that allowing infringement for export of components under 271(f) creates “an incentive to move their research aid development abroad.”
Canadian Government’s Amicus Brief in Support of the Petition
In a rare move, the Government of Canada filed a brief supporting the petition for rehearing en banc. The brief notes that the panel opinion does not include any discussion of the principles of comity and international law that should be considered when determining the extent that U.S. laws should be interpreted to limit activities taken on foreign soil.
“The reissued panel opinion lacks any acknowledgment or discussion of the effect of, or the effect upon, long-established international understandings and agreements regarding national jurisdiction over intellectual property. Because the decision of the panel was neither explained nor justified in terms of contemporary, internationally-accepted principles of national jurisdiction, the opinion raises questions concerning fundamental principles upon which this international intellectual property system has harmoniously been based for well over a century.”
The brief recognized that the eventual conclusion may well be that patent laws should extend transnationally. However, the the thrust of this brief is that an expansion of extraterritorial application of the law should include a thorough analysis of the international implications.
Canadian Chamber of Commerce in Support of the Petition
The group of Canadian businesses argue that the standards created by the RIM opinion create confusion by the artificial distinction between system and process claims. Further, the group argue that the court should respect the rule of comity when construing a statute.
As the Supreme Court recently stated, courts “ordinarily construe[] ambiguous statutes to avoid unreasonable interference with the sovereign authority of other nations.” F. Hoffman-La Roche v. Empagran, 542 U.S. 155 (1994).
Seven Networks, Inc. Brief in Support of the Petition
Seven Networks argues simply that patents are “national in scope.” And, without congressional action, patents should remain national in scope.
On its face, 35 U.S.C. §271(a) is national in scope, and the statute has no extraterritorial reach. It applies to “whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States”. When a statute is silent as to its extraterritorial application, the presumption is that the statute does not have extraterritorial effect.
With reference to “control and beneficial use” standard derived from Decca, Seven argued that Decca’s decision required ownership of the foreign-located system elements. Because RIM customers do not own the Routers located in Canada, they cannot be said to have control or be beneficially using that element.
Information Technology Association of Canada Brief in Support of the Petition
The ITAC brief takes the stance that method and system claims should be treated consistently. ITAC correctly points out that it is often quite easy to draft a “system” claim that contains the same limitations as a parallel “method” claim.
NTP’s Consolidated Response to the Amicus Briefs
No amici disputes the fact that one of the patents does not even give rise to the issue of territoriality (NTP wants to avoid this altogether and just get paid).
The Canadian Gov’t Brief confirms that U.S. patent laws apply when the RIM system is used Within the U.S.
Microsoft supports the decision finding infringement of the system claims.
The Canadian Chamber of Commerce seeks an improper advisory opinion (on product-by-process claims).
The ITAC brief, prepared by RIM’s patent firm (Kirkland & Ellis) merely rehashes RIM’s old arguments.
Seven Networks hopes to avoid infringement by placing its own routers abroad.
Intel’s Amicus Brief in Support of the Petition
In a brief supporting an en banc rehearing, Intel first noted that this issue is of great importance to today’s economy where many thousands of businesses operate multinationally. Like RIM, Intel could find no “principled or policy basis” for the outcome of a multinational infringement case to depend on the form of the preamble of the claim.
There is no reason to hold that practicing every step is essential to infringement of a claimed process, yet hold that use of every component is not essential to infringement of a claimed system.
Regarding 271(f), Intel discussed the fact that, although the four recent Federal Circuit cases discussing 271(f) purport to distinguish one another, “the ultimate holdings are difficult to square, and they lack a common analytical approach.”(See, Eolas, AT&T, Pellegrini, & NTP). “The Court has yet to take a consistent and holistic view of infringement liability in the transnational context.”
Finally, Intel asked the court to place the burden on patent drafters — arguing that it is possible to draft claims to virtually any invention that avoids the need to extend 271(a) to cover extraterritorial activities.
In a brief filed specifically in response to Intel’s brief, RIM argued (i) that it had been filed after the deadline and thus should be considered untimely; (ii) that Intel does have a financial interest in the case; and (iii) that Intel’s brief simply rehashes old arguments.
After losing at the 11th Circuit, the FTC has filed a petition for certiorari asking the Supreme Court to hear its appeal. In a March 2005 decision, the 11th Circuit Court of Appeals set aside an FTC order that barred Schering-Plough from settling an infringement suit with generic makers regarding the patented blood pressure drug K-Dur. The FTC had concluded that the settlement was an “unreasonable restraint of trade.” The 11th Circuit, however, disagreed, finding that payment from a patent holder to a generic competitor cannot be the sole basis of a violation of antitrust law. Accordingly, the court SET ASIDE the decision of the Federal Trade Commission and VACATED its cease and desist order.
In its petition for certiorari, the FTC presents two questions to the Court:
1. Whether an agreement between a pharmaceutical patent holder and a would-be generic competitor, in which the patent holder makes a substantial payment to the challenger for the purpose of delaying the challenger’s entry into the market, is an unreasonable restraint of trade.
2. Whether the court of appeals grossly misapplied the pertinent “substantial evidence” standard of review, by summarily rejecting the extensive factual findings of an expert federal agency regarding matters within its purview.
In its supporting brief, the FTC argues that agreements between competitors should not be per se lawful simply because they are within the “potential” reach of a patent claim. The Public Patent Foundation (PubPat) supported the FTC at the Eleventh Circuit and will likely file an Amici Brief in support of the FTC’s petition.
In patent prosecution, the Patent Office fees are usually quite low when compared to the cost of hiring a patent attorney. I’m predicting that the usual equation is not quite true for Angiotech International who was recently asked to pay $1.25 Million in application filing fees for a patent application having about 10,000 claims. (File Attachment: Fee Due.pdf).
As would be expected, the patentee quickly submitted an amended specification that cut the disclosure to three independent claims and 96 dependent ones — thus reducing its PTO bill to only two grand.
As Greg Aharonian noted, it is lucky that the applicant was a small entity — otherwise the fee would have been over $2,000,000. (Published Application)
Gottling successfully appealed an Examiner’s rejection based on his argument that there was no motivation for combining the cited prior art references within the references themselves.
Obviousness cannot be established by combining prior art to produce the claimed invention absent some teaching or suggestion supporting the combination. The mere fact that the prior art may be modified in the manner suggested by an examiner does not make the modification obvious unless the prior art suggested the desirability of the modification.
In this case, the Board found that the Examiner had not explained “why a person of ordinary skill in the art would have found it obvious” to combine the references in the manner proposed by the Examiner.” In particular, the Board noted that neither reference specifically recognized the advantages discussed in Gottling’s application.
KSR v. Teleflex, now before the Supreme Court asks the court to review the “teaching-suggestion-motivation test” that was the basis of the Gottling decision.
With its new leadership corps, the USPTO is moving forward with a number of initiatives to address the concerns of patent holders, businesses, and the public.
A major project launched last fall is the anti-counterfeit program StopFakes! (www.stopfakes.gov). Now, the PTO has created a small business focused initiative to “help small business owners protect their intellectual property from overseas piracy and counterfeiting. Information on the new small business initiative is available online here: www.uspto.gov/smallbusiness.

FILE HISTORIES: A Patently-O Reader is looking for the filewrappers for Patent Nos. 5,894,554 and 6,415,335. These are reportedly being asserted by a company called EpicRealm (Story). Let me know if you have them.
EXPERIMENTAL USE: In a newly published paper in the Federal Circuit Bar Journal, Professor Hal Wegner argues that the U.S. should have a clear experimental use defense that would allow experimentation on a patented invention.
Westbrook v. Gray, 75 U.S.P.Q.2d 1607 (BPAI) (UNPUBLISHED).
In a short decision, the Patent Board confirmed that “examination must be complete in an application before an interference involving that application is initiated.”
Applicant Gray filed a petition with the Board asking for guidance as to whether it should file a motion suggesting the declaration of an interference. Finding that examination of the application had not been completed, the Board held that an interference would be premature.
Under MPEP 2301.01, before a claim should be “considered as the basis for the count of an interference, the claim should be allowable and in good form.”
Storagetek v. Custom Hardware Engineering (Fed. Cir. 2005)
Normally, the unauthorized duplication of computer software violates the exclusive right of the copyright holder. Section 117(c) of the Copyright Act, however, authorizes the copying of a computer program for purposes of maintaining or repairing a machine if the “copy is made solely by the virtue of activation of [that] machine”.
In a case of first impression, the Federal Circuit addresses the extent of this protection offered by 17 U.S.C. § 117(c). The Court of Appeals, relying on definitions in 17 U.S.C. § 117(d), held that § 117(c) protects maintenance and repair as two different activities. “Repair,” according to the Federal Circuit, is restoring a broken machine to its original specifications. “Maintenance,” on the other hand, has “a much broader temporal connotation” that “encompass[es] monitoring systems for problems [and] not simply fixing a single, isolated malfunction.” Thus, the Federal Circuit found erroneous the district court’s conclusion that only repair activities are protected under Sec. 117(c).
Furthermore, the Court of Appeals also found DMCA provisions likely not applicable. Circumvention of a technological measure providing access to a copyrighted work is not a violation of DMCA, according to the Federal Circuit, unless it “infringes or facilitates infringing a right protected by the Copyright Act.” Finally, the Court of Appeals did not agree, based on material factors, that the copyrighted work in question should receive trade secret protection.
The Federal Circuit thus vacated the district court’s grant of a preliminary injunction to Storage Technology and remanded for further proceedings. Judge Rader, in dissent, decried the majority’s decision as “destroy[ing] copyright protection for software that continually monitors computing machine behavior.”

MEMC Electronic Materials v. Mitsubishi Materials (Fed. Cir. 2005).
MEMC sued Mitsubishi for infringement of its patent directed to the preparation of high quality single crystal silicon for the semiconductor industry. The district court dismissed the claims on summary judgment — finding no evidence of infringement or inducement.
On appeal, the CAFC affirmed the rejection of the direct infringement claim, but reversed on inducement. The panel found that the defendant (i) knew of the alleged direct infringer’s activities; (ii) provided technical support to the alleged direct infringer via e-mail; (iii) sent a shipment to the alleged direct infringer to address technical problems; (iv) visited the alleged direct infringer’s site to provide further technical support; and (v) knowledge of the patent itself. This record swayed the CAFC to reverse the district court’s holding that “a reasonable jury could not find intent to induce infringement.”
Specifically, the CAFC noted the series of e-mails provide “sufficient circumstantial evidence . . . that SUMCO intended to encourage those [potentially infringing] activities.”
As Cathy Kirkman notes in her excellent Silicon Valley Media Law Blog, the CAFC drew a parallel with the the recent Supreme Court Grokster copyright inducement opinion. Quoting Grokster, the appellate court held that evidence such as “advertising an infringing use or instructing how to engage in an infringing use, show an affirmative intent that the product be used to infringe.”
AquaTex appealed a summary judgment of noninfringement arguing that the district court had improperly applied prosecution history estoppel to limit use of the doctrine of equivalents.
On appeal, the CAFC “decline[d] to give the prosecution history much weight.” In its decision the Court quoted Phillips for the conclusion that the prosecution history is an ongoing negotiation that “often lacks the clarity of the specification and thus is less useful for claim construction.” Although the CAFC disagreed with the lower court’s basis of decision, ultimately, the panel affirmed the claim construction.
Regarding the doctrine of equivalents, the CAFC could not find the requisite “clear and unmistakable surrender of subject matter required to invoke argument-based prosecution history estoppel.”
Tap Pharmaceutical v. OWL Pharmaceuticals (Fed. Cir. 2005).
In an action for infringement of several pharmaceutical patents, the Federal Circuit upheld the district court’s findings that the generic drug-maker (OWL) had infringed two of the plaintiffs’ (Tap et al) patents.
Broad Scope Derived from Specification: Claims which described the patented compound as “comprising a copolymer … of lactic acid and … of glycolic acid” were interpreted by the appellate panel to also encompass copolymers “produced by any method.” Although the specification only provided examples of copolymers made from lactic and glycolic acid, it did note that the polymer “may be produced by any method.”
Disclaimer Based On Foreign Prosecution: Regarding foreign prosecution history, the CAFC gave little weight to statements made by the patentee to an Examiner in the European Patent Office that the invention did not include compounds made from lactide or glycolide. The European Examiner had rejected the claims after this argument was made, finding that the compounds which the patentee had attempted to disclaim were not different from those made from lactic and glycolic acid. Therefore, because the European claims were later allowed on other grounds, and because the patentee had not made this argument before the USPTO, the patentee must have “receded from that characterization of the claims,” and thus these statements should be given little weight in the process of claim construction.
Even Common Words Construed According To Specification: A second claim directed to “particles containing a water-soluble drug” was interpreted to encompass only particles which included both 1) the drug substance, and 2) a drug-retaining substance, because the drug-retaining substance was included in all the examples in the specification and was listed as a benefit of the invention. The court held that the term “containing,” while not a technical term, helped to describe the patented technology and therefore “cannot be defined by some ordinary meaning isolated from the proper context.” Thus, the district court was correct to look to both intrinsic and extrinsic evidence to properly interpret the claim.
The Federal Circuit thus affirmed the district court’s claim construction as to both patents.
NOTE: This post was written by Rebecca Brown. Ms. Brown is a law clerk at MBHB and a student at Northwestern University School of Law.
As Attorney Jason Rantanen pointed out in a recent e-mail, there is a clear distinction between the prosecution history disclaimer and prosecution history estoppel. The disclaimer doctrine is related to “claim construction for the purposes of literal infringement” while the estoppel doctrine bars the assertion of DOE under Festo.
Broadcast Innovation v. Charter Communications (Fed. Cir. 2005).
The district court found Broadcast’s patent to be anticipated because its priority date was more than one year after the publication of an Australia PCT application on the same subject matter filed by the same parties. The asserted patent failed to claim a specific reference to the PCT application, but did claim priority to a U.S. application that, in turn, claimed priority to an earlier PCT filing.
On appeal, the CAFC determined that the district court had applied the wrong priority date to the asserted patent — finding that the chain of priority was sufficient to fall within the requirements of 35 U.S.C. 120.
[T]he applicant filed the [US priority application] on July 18, 1995, as the U.S. national stage application of the original PCT application. However, July 18, 1995 is not the “U.S. filing date” of the [US priority application]. Specifically, under 35 U.S.C. § 363, the international filing date of a PCT application is also the U.S. filing date for the corresponding national stage application.
Thus, the court clarified that Section 120’s reference to a later filed application having “the same effect . . . as though filed on the date of the prior application” means that the later application will be treated as having the effective filing date of the prior application.
Patients Not Patents v. Medimpex United (Dist. D.C. 2005).
Under Section 292 of the Patent Act, “[a]ny person may sue” a party that falsely marks a product as “patented” or “patent pending.” In such cases, the fine is limited to $500 per offense.
In a court filing on Tuesday, August 16, 2005, a D.C. nonprofit known as “Patients not Patents, Inc.” filed a Section 292 complaint against Medimpex United, maker of Xalex Weight Management Gel.
The complaint, signed by PNP’s director Jeffrey Light, alleges that Medimpex’s products have been falsely marked as “patented” and sold through various marketing channels, including a list of internet retailers.
There is little precedent on Section 292, however, in the recent Clontech case, the Federal Circuit determined that the statute requires patentees have a good faith believe that the marked article falls within the subject matter of the patent. According to the CAFC, marking must be reliable in order to permit free and fair competition and commerce. In an e-mail, Light commented that this statute provides a way of “linking patent issues to consumer protections.”

NTP v. Research-in-Motion (en banc review). 
In its brief, RIM questioned the panel decision that 
“The reissued panel opinion lacks any acknowledgment or discussion of the effect of, or the effect upon, long-established international understandings and agreements regarding national jurisdiction over intellectual property. Because the decision of the panel was neither explained nor justified in terms of contemporary, internationally-accepted principles of national jurisdiction, the opinion raises questions concerning fundamental principles upon which this international intellectual property system has harmoniously been based for well over a century.”
