Patently-O Bits and Bytes

USPTO Patent News:

  • Patent number 12 million issued on Tuesday, June 4, 2024, to Pacific Biosciences of California.  The patent covers particular labeled nucleotide analogs that include an avidin protein for use in analyzing enzymatic reactions and molecular recognition events, such as single-molecule real-time nucleic acid sequencing. From the file history, it looks like David Roise was the lead attorney on the case.
  • Derris Banks has been appointed as the Regional Director of the USPTO’s Elijah J. McCoy Midwest Regional Office (Detroit), where he will oversee outreach efforts while serving inventors and entrepreneurs in the Midwest region.  Banks has been at the USPTO since joining as an examiner in 1994, rising to various leadership positions.  Damian Porcari, who led the office for five solid years, retired in 2023.
  • Several comment periods are still open at Regulations.Gov. Yesterday the period for comments closed on upcoming USPTO fee increases. At least 30 comments were submitted, including those from the AIPLA who “objects to the major policy shift wherein front-end fees are being added not only to recover aggregate costs, but change applicant behavior and implement significant policy changes, including large fee increases for claiming benefits of earlier effective filing dates, filing of Requests for Continued Examinations (“RCEs”), terminal disclaimer submissions, and for filing of large Information Disclosure Statements (“IDSs”).”  [This sentence was almost certainly written by a patent attorney.]

Patent Rights and Cell-Free DNA cancer testing

by Dennis Crouch

I have been following the ongoing case of Natera v. NeoGenomics that is currently on appeal before the Federal Circuit. Docket No. 24-1324. The technology in these cases has amazing potential and I have several friends who have used these techniques to detect early stage cancer.

The particular litigation here centers on Natera’s US Patent No. 11,519,035 issued on December 6, 2022 that covers a method of detecting cancer through analysis of cell-free DNA (cfDNA) obtained from blood samples.  The basic idea is that small fragments of DNA that are released into the bloodstream by cells, including cancer cells. High throughput extraction and sequencing technologies can then be used to detect mutations and their potential associated risk factors, including the presence of cancer and the specific type of cancer. cfDNA cancer screening has lots of advantages, most notably, it is almost non-invasive (blood sample) and provides potential early across the entire body.  It can be particularly effective for detecting reemergence of cancer for someone in remission because the particular mutation is already known.  This is known as a “tumor-informed” test.

Natera’s ‘035 patent is directed to methods for amplifying and sequencing cell-free DNA (cfDNA) to detect cancer. The claimed invention involves three key steps: (1) tagging cfDNA with universal adaptors, (2) amplifying 25-2,000 single nucleotide polymorphism (SNP) loci in a single reaction volume, and (3) performing massively parallel sequencing.  Each of these steps were known in the prior art, but the combination of all three appears to be new. NeoGenomics is accused of infringing through its use of its RaDaR, an independently developed cancer-detection test that purportedly employs a similar process for analyzing cfDNA to provide highly sensitive detection of cancerous mutations. NeoGenomics disagrees, arguing the claims require the tagging and targeted amplification to occur in separate PCR reactions with different primer sets, and that its approach combines this process.

A New Horizon: Design Patent Practitioner Bar Proposed by USPTO

by Dennis Crouch

The United States Patent and Trademark Office has proposed a rule to create a separate design patent practitioner bar. The USPTO is publishing this proposal in the Federal Register on May 16, 2023 (link below to the prepub).

As it stands today, there is a single patent bar that applies to those practicing in patent matters before the USPTO, covering utility, plant, and design patents.  And, even though design patents cover ornamentally, the current rules require that the  design patent practitioner be an engineer or scientist.

The proposed rule aims to establish an additional separate bar for those who only specialize in design patents, ensuring that they have the necessary qualifications, while opening the door to non-engineers.  The proposal appears to not affect those already registered to practice. Existing patent practitioners will continue to practice as before, and new applicants who meet the current criteria, including passing the existing registration exam, will also be permitted to practice in all patent matters, including design patent matters.

In Fall 2022, the USPTO asked for comments on proposals in this direction and received mostly positive comments. Stakeholders acknowledged that the move would encourage broader participation in the patent system.

The proposal would still have a ‘technical’ requirement, typically a degree in one of the following: industrial design, product design, architecture, applied arts, graphic design, fine/studio arts, or art teacher education. The degree requirements here align with the current hiring practices of the USPTO for design patent examiners.  In addition to the degree requirements, applicants would have to meet the other requirements to register for the bar, including taking and passing the current registration examination and passing a moral character evaluation.

The USPTO will accept comments on the proposed rulemaking through August 14, 2023 via the regulations.gov portal.

Attorney Fees on Undecided Inequitable Conduct Issues

by Dennis Crouch

United Cannabis Corp (UCANN) vs. Pure Hemp Collective, — F.4th — (Fed. Cir. 2023)

The UCANN vs. Pure Hemp patent case has come to a close with the Federal Circuit affirming the district court’s decision to deny attorney fees to Pure Hemp. The original infringement lawsuit was filed in 2018, with UCANN suing Pure Hemp for infringing US Patent No. 9,730,911, covering various high concentration cannabis and CBD extract formulations. During the litigation, UCANN filed for bankruptcy, causing the case to be stayed, and eventually, the parties stipulated to a dismissal of the infringement claims with prejudice. However, the stipulated dismissal did not include any discussion of attorney fees — leading to the current appeal.

Following the dismissal, Pure Hemp moved for attorney fees and sanctions, arguing that UCANN’s counsel committed inequitable conduct during patent prosecution and that UCANN’s litigation counsel had a conflict of interest. The district court sided with UCANN and denied attorney fees, stating (1) that Pure Hemp was not the prevailing party and (2) that Pure Hemp did not prove that the case was exceptional. The Federal Circuit has now affirmed the decision, finding that the district court did not abuse its discretion in finding the case unexceptional. Although district court the district court erred in not finding Pure Hemp to be the prevailing party, the error was harmless.

Bringing Home the Bacon with Joint Inventorship

Guest Post by Jordan Duenckel.  Jordan is a second-year law student at the University of Missouri, head of our IP student association, and a registered patent agent.  He has an extensive background in chemistry and food science.

HIP, Inc., v. Hormel Foods Corp., 2022-1696, — F.4th — (Fed. Cir. May 2, 2023)

Joint inventorship requires a substantial contribution to the invention. In the decision HIP, Inc. vs. Hormel, Judge Lourie writes for a unanimous panel to reverse a district court’s determination of joint inventorship involving a new process for precooking bacon. US Patent 9,980,498 has four inventors that are employees of and assigned their interest to Hormel.  HIP sued Hormel, alleging that David Howard was either the sole inventor or a joint inventor of the ’498 patent. The district court determined that Howard was a joint inventor based solely on his alleged contribution to the infrared preheating concept in independent claim 5.  

Bacon is an interesting food with unique preservation and cooking properties. Being a cured product, for food safety reasons, no additional cooking of the bacon is needed when bought off the shelf in a refrigerated section. Of course, most people are not consuming the bacon without additional cooking and some companies will precook the product for consumer convenience. When precooking, Hormel is trying to avoid the loss of salt, and therefore flavor, through condensation and prevent the creation charred off flavors (as opposed to the desirable char on a steak).  

 In the process of viability testing the new method, prior to filing the application, the inventors consulted with David Howard of Unitherm, HIP’s predecessor, to discuss methods related to Unitherm’s cooking equipment to create a two-step process of preheating then a higher temperature step. After some difficulties, Hormel leased the equipment and returned to their own R&D lab. The method created, the subject matter of the ‘498 patent, involves a first step that allows the fat of the bacon to seal the surface of the bacon and prevent condensation. The charring was remedied by adjusting the heating method of the oven in the second step of high-temperature cooking. In Hormel’s product development, Hormel tried an infrared oven and a conventional spiral oven.

HIP argued that Howard contributed to the ‘498 patent in the preheating by hot air in claim 5 and/or preheating with an infrared oven in claim 5.  Claim Five reads in the relevant part:  

  1. A method of making precooked meat pieces using a hybrid cooking system, comprising: preheating meat pieces in a first cooking compartment using a preheating method selected from the group consisting of a microwave oven, an infrared oven, and hot air to a temperature of at least 140º F. to create preheated meat pieces…

On appeal, Hormel argues that Howard’s contribution is well-known in the art and insignificant when measured against the full invention. With inventorship being a question of law, and the issuance of a patent creating a presumption of inventorship, an alleged joint inventor must provide clear and convincing evidence to substantiate their claim. In evaluating whether a significant contribution was made by Howards, the parties apply the test from Pannu v. Iolab Corp., 155 F.3d 1344, 1351 (Fed. Cir. 1998). The test requires that the alleged joint inventor: 

(1) contributed in some significant manner to the conception of the invention; (2) made a contribution to the claimed invention that is not insignificant in quality, when that contribution is measured against the dimension of the full invention; and (3) did more than merely explain to the real inventors well-known concepts and/or the current state of the art. 

Analyzing the second Pannu factor, the Court found that the alleged contribution of preheating meat pieces using an infrared oven to be insignificant in quality because it was mentioned only once in the patent specification as an alternative heating method to a microwave oven and was recited only once in one Markush grouping in a single claim. In contrast, preheating with microwave ovens and microwave ovens themselves were prominently featured throughout the specification, claims, and figures. The examples and corresponding figures also employed procedures using preheating with a microwave oven, but not preheating with an infrared oven.  

Infrared heating seems to have been an afterthought in the creation of the two-step precooking method. Whatever discussions Howard might have had about the importance of the infrared, Hormel seems to have focused on microwave heating to solve the condensation problem. From one step further back, it seems absurd to permit joint ownership by a cooking equipment manufacturer when the significant discoveries and refinements of the methods were made in Hormel’s R&D facility without Howard present. The prevention of condensation and avoiding the char flavor were both made independent of Howard’s contributions. Considering the second Pannu factor, the reversal of inventorship seems appropriate.  

Establishing Guidelines for Patent Damages: The Garretson v. Clark Case of 1884

by Dennis Crouch

Calculating damages for patent infringement can be a complex task, particularly when the invention is an improvement to an existing machine or product.  The Supreme Court’s 1884 decision in Garretson v. Clark, 111 U.S. 120, helped establish a rule requiring apportionment in cases involving improvement patents.

The plaintiff, Garretson held two patents covering improved mop heads and sued the defendants for infringement.  The lower court sided with the patentee — finding the claims valid and infringed and also issued an injunction to halt ongoing infringement.  However, the court balked at awarding the requested back-damages for past infringement.

The patentee had offered a simple lost-profit damage calculation.  In particular the court was presented with evidence showing how much profit the patentee made from the sale of each mop, and the patentee asked the court to force the defendant to pay that amount for each of infringing mop.  The circuit court judge Samuel Blatchford appointed NY patent attorney George J. Sicard to conduct an accounting.  Sicard came back with a recommendation of $0 in damages, and Blatchford agreed.

The issue here is that the patent covered an improvement to a mop, but the patentee was seeking damages for the entire profits associated with the mop — not just the value of the improvement.  In his opinion, Blatchford wrote:

The patentee must in every case give evidence tending to separate or apportion the defendant’s profits and the patentee’s damages between the patented feature and the unpatented features, and such evidence must be reliable and tangible, and not conjectural or speculative; or he must show, by equally reliable and satisfactory evidence, that the profits and damages are to be calculated on the whole machine, for the reason that the entire value of the whole machine, as a marketable article, is properly and legally attributable to the patented feature.

Garretson v. Clark, 10 F. Cas. 40, 44 (C.C.N.D.N.Y. 1878).  The plaintiff has the burden of proving damages, but its theory of damages utterly failed. And, no other damages evidence was presented. The effective result was no damages.

At the time of the decision, Blatchfort was a circuit court judge. In 1882, he was nominated by President Chester Arthur to the U.S. Supreme Court.  Because of the long backlog at the time, Blatchfort reached the court before the case was heard (even though it was directly appealed).  The Supreme Court finally got around to hearing the appeal in 1886 and affirmed in an opinion by Justice Field.

The high court quoted Blatfort’s decision as I have done above and  also remarked that for improvement patents, “the patentee must show in what particulars his improvement has added to the usefulness of the machine or contrivance. He must separate its results distinctly from those of the other parts, so that the benefits derived from it may be distinctly seen and appreciated.” Garretson v. Clark, 111 U.S. 120 (1884).

The decision helped establish a clear rule for patentees to follow when claiming damages for improvements in existing machines or contrivances. It emphasized the presentation reliable and tangible evidence to apportion profits and damages between patented and unpatented features or evidence to demonstrate that the entire value of the product is attributable to the patented feature.

= = =

An interesting aside from this case is that the defendant – Charles B. Clark – is also co-inventor of one of the two asserted patents.  Clark had transferred his rights to a third party, and Garretson bought them up.  The case involves sales of 100,000+ mops.

= = =

Note here that this case was brought in equity rather than at law and so that raises a major difference between current cases, and we had different statutory language under the 1870 Act.  A lot of our 1800s patent cases have quirks that leave them not susceptible to direct application to today’s cases.  Still, I be but they still provide some amount of foundational guidance and gives a chance to observe the evolution of the legal principles we know today.

Amgen Scores Partial Victory in Efforts to Maintain OTEZLA Exclusivity

By Chris Holman

Amgen Inc. v. Sandoz Inc., 2023 WL 2994166, — 4th —   (Fed. Cir. Apr. 19, 2023)

In 2019, Amgen acquired worldwide rights to apremilast (OTEZLA) from Celgene $13.4 billion in cash, in connection with Celgene’s merger with Bristol-Myers Squibb. Apremilast was the only oral, non-biologic treatment for psoriasis and psoriatic arthritis, and in 2020 apremilast generated $2.2 billion for Amgen.

At the time Amgen’s acquired apremilast, Celgene was involved in Hatch-Waxman litigation with numerous generic challengers, including Sandoz. Celgene had asserted three of its 11 Orange Book-listed patents against Sandoz, and in 2020 Amgen was substituted as plaintiff.

The primary patent asserted is U. S. Patent 7,427,638, which is directed to pharmaceutical compositions comprising stereochemically pure apremilast. The original expiration date of this patent was in 2024, but the patent received a patent term extension of more than three years, resulting in an effective patent expiration date of February 16, 2028, according to the Orange Book.

Celgene also asserted U. S. Patent 7,893,101, which is directed to enantiomerically pure solid forms (e.g., crystalline polymorphic forms) of apremilast. This patent is due to expire December 9, 2023.

The third patent asserted by Celgene was U. S. Patent 10,092,541, directed to methods for treating a patient using dose titration of apremilast. According to the Orange Book, this patent was set to expire on May 29, 2034.

The district court found the claims of the ‘638 and ‘101 patents to be infringed and not invalid, and enjoined generic apremilast until the expiration of the ‘638 patent in February 2028. On appeal the Federal Circuit affirmed, an outcome that Amgen characterizes as a win.

On the other hand, the district court found the asserted claims of the ‘541 patent to be invalid for obviousness, which reportedly “pleased” Sandoz because the ruling “enables Sandoz to launch [its] generic apremilast product in the U. S. in 2028, six years prior to the expiry date of the latest-expiring Amgen patent asserted in litigation.”  On appeal, the Federal Circuit affirmed with respect to the obviousness of the ‘541 patent.

Here is a brief overview of the court’s decision regarding the asserted obviousness of these patents.

The ‘638 patent claims apremilast, which is the stereochemically pure (+) enantiomer of a compound falls that within a class of molecules referred to as phosphodiesterase-4 (“PDE4”) inhibitors.  Sandoz’s obviousness argument was based primarily upon a prior art Celgene patent, U. S. Patent 6,020,058, which includes an Example 12 that describes a racemic mixture containing apremilast, but that does not disclose the purified (+) enantiomer. The Federal Circuit found that the district court had not erred in holding that Sandoz had not proven that a skilled artisan would have had sufficient motivation to purify the (+) enantiomer from the racemic mixture disclosed in Example 12, nor that a skilled artisan would have had a reasonable expectation of success in resolving that mixture into its enantiomeric components, given the unpredictable nature of resolving racemic mixtures.

The Federal Circuit further found that the district court had not erred in its finding of strong objective indicia of nonobviousness, particularly given the unexpected potency of apremilast relative to the apremilast-containing racemic mixture disclosed in Example 12. The court credited testimony from a Celgene researcher listed as an inventor on the ‘638 patent, who noted a 20-fold difference in potency between apremilast alone and the racemic mixture, and stated that the inventors “didn’t expect a 20-fold difference in potency… Normally, if a racemate is a 50/50 mixture of two enantiomers, you might expect a two-fold difference in potency, all things being equal.” The district court also did not err in determining that apremilast satisfied a long felt need for an improved psoriasis treatment suitable for oral administration, that others in the field had tried and failed to develop other PDE4 inhibitors as drugs, and that there had been a degree of skepticism about the safety of apremilast because of its structural similarity to thalidomide, a drug notorious for its teratogenic effects in fetuses leading to severe and debilitating birth defects.

The issue with respect to the ‘101 patent was whether it could rely upon the filing date of a provisional application to which it claims priority. The ‘101 patent claims crystalline Form B of apremilast, and the provisional application includes an Example 2 which discloses a synthetic procedure for preparing apremilast. Although Example 2 does not explicitly disclose that the resulting apremilast has the Form B crystalline structure, Amgen provided the court with the results of over a dozen experiments following the procedure of Example 2, all of which resulted in crystalline Form B of apremilast, while Sandoz had provided no evidence to establish that Example 2 was capable of producing a crystalline Form other than Form B. Although the district court had based its holding on its conclusion that the provisional application inherently disclose crystalline Form B of apremilast, the Federal Circuit found that it did not need to reach the issue of inherent disclosure because the evidence established that Example 2 actually disclosed crystalline Form B of apremilast, albeit without specifically disclosing the crystal structure of the resulting product.

The ‘541 patent claimed a method of treating a patient with apremilast that basically involves starting with a relatively low dose and, over a course of days, gradually increasing the dosage to arrive at a full dosage which is significantly higher than the initial dosage, i.e., a dose-titration schedule. The court found this to be an obvious method, in view of prior art disclosing a similar dosage schedule. The Federal Circuit observed that, as a general matter, varying doses in response to the occurrence of side effects is well-known and obvious to the skilled artisan.

Federal Circuit: Construing the Term “A” once Again

by Dennis Crouch

In Salazar v. AT&T Mobility LLC, the Federal Circuit affirmed the district court’s judgment of noninfringement. Once again, the Federal Circuit was called upon to interpret the claim term “a,” this time to determine if Salazar’s claim requiring “a microprocessor” was limited to a single microprocessor. While “a ___” is usually interpreted to include “one or more ___,” the court upheld Judge Gilstrap’s narrower singular construction in this case, finding it limited by later references to “said microprocessor.”

Salazar’s US Patent No. 5,802,467 claims a communication system for interacting with multiple external devices. The system comprises “a microprocessor” that generates reprogrammable communication protocols, a memory device for efficient storage of command code sets retrieved by “said microprocessor,” a user interface for user selections and menu displays rendered by “said microprocessor,” and an infrared frequency transceiver coupled to “said microprocessor” enabling bidirectional communication with external devices.

AT&T systems may have the capability to achieve all these steps, but the defendant argued that each step utilized different processors or multiple processors. Thus, as the District Court explained, the dispute centered on “whether the claims require one microprocessor that is capable of performing the recited ‘generating,’ ‘creating,’ ‘retrieving,’ and ‘generating’ functions.” According to the district court construction, the patentee needed to identify a single processor that performed “all the functional (and relational) limitations recited for ‘said microprocessor.'” As a result, the court found no infringement. The Federal Circuit affirmed this decision on appeal.

While the indefinite article “a” is generally interpreted broadly as not limited to one item, this presumption can shift when necessitated by the patent documents. In this case, the patentee repeatedly used “said microprocessor” to refer back to the already claimed term in a way that “reinvokes [the] non-singular meaning” of the word “a.” Slip Op. (quoting Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338 (Fed. Cir. 2008). According to the court, an alternative interpretation would ignore the meaning of “said.”

The key takeaway is that each time the claim uses “said microprocessor,” it refers back to the originally identified microprocessor. This interpretation prevented the argument that the claim covers the use of multiple microprocessors working together to achieve the described functionality.  Non-infringement affirmed.

= = = =

The jury sided with the patentee on anticipation. AT&T also appealed this issue. However, the Federal Circuit declined to hear the question, holding that AT&T failed to move for a Rule 50(a) JMOL before the case was submitted to the jury, thus waiving its right to appeal the sufficiency of the evidence on that issue.

$469 Million: There and Gone

ClearPlay v. Dish Network (D.Utah 2023)

Earlier in March 2023, a Utah jury sided with the patentee ClearPlay – find that Dish Network infringed two “clean movie” patents used to to skip the naughty bits of a video program. US7577970 (Claims 28 and 33); and US6898799 (Claim 12).  The jury went on to award a “reasonable royalty” of $469 million.

Hold that pause button.  This week, Judge Nutter rejected the jury verdict and instead granted the defendant’s motion for Judgment as a Matter of Law.  Nutter concluded that the patentee had not shown either literal infringement or infringement by equivalents.  The court ordered DISH to prepare a draft order for his signature that adopts the rational from its briefing.

The draft order will contain support, citations, and consistent rationale from its briefing; transcript references from DISHs appendix (which should be used extensively in the draft order); and references to contrary positions taken by ClearPlay to illustrate the conflicts that this ruling resolves.

Minute Entry of March 21.   The case has been pending since 2014.

Roundup Ready 2 Patent Litigation

Bayer CropScience v. Pierce, et al. (E.D. Mo 2023)

Bayer and its subsidiary Monsanto have filed a new set of patent infringement lawsuits against farmers who saved seeds and replanted them in violation of Monsanto Roundup Ready patents and license agreements.  Monsanto’s original patents on genetically modified plants have all expired. But, the company now primarily sells Roundup Ready 2 – Xtend seeds for soybeans and cotton. And those new lines are covered by new patents. Here, the company has asserted United States Patent Nos 9,944,945  and 7,838,729.

  • The ‘729 patent has a 2007 priority date and claims plants genetically modified with a particular DNA sequence to express dicamba monooxygenase. This allows the plant to quickly catalyze and degrade the herbicide dicamba; thus allowing use of dicamba herbicide as an addition/alternative to glyphosate in the common situation involving herbicide resistant weeds.
  • The ‘945 patent has a 2005 priority date and claims a transgenic soybean plant modified with a gene that confers increased glyphosate tolerance so that more glyphosate can be used without harming the soybean.

Each of the six new infringement lawsuits infringe both patent infringement as well as breach of contract for saving and planting seed down in the Missouri Bootheel.

  • Bayer CropScience LP v. Robert O. Pierce, Docket No. 4:23-cv-00088 (E.D. Mo. Jan 25, 2023)
  • Bayer CropScience LP v. Danny Glass, Docket No. 4:23-cv-00087 (E.D. Mo. Jan 25, 2023)
  • Bayer CropScience LP v. Greg Duffy, Docket No. 4:23-cv-00086 (E.D. Mo. Jan 25, 2023)
  • Bayer CropScience LP v. Caleb Duffy, Docket No. 4:23-cv-00085 (E.D. Mo. Jan 25, 2023)
  • Bayer CropScience LP v. Michael Hodel, Docket No. 4:23-cv-00084 (E.D. Mo. Jan 25, 2023)
  • Bayer CropScience LP v. Brian G. Irions, Docket No. 4:23-cv-00083 (E.D. Mo. Jan 25, 2023)

I expect that Bayer will easily win these cases, but we’ll see. So far, none of the farmers have lodged an appearance in court.
