101 Ways Not to Invalidate: Federal Circuit Rejects Sua Sponte Eligibility Ruling

Patent

by Dennis Crouch

The Federal Circuit's recent decision in Astellas v. Sandoz emphasized the importance of the "party presentation principle" -- that, for the most part, courts should rely upon the parties to frame the issues that need a ruling.  Visiting Delaware, Nebraska District Court Judge Bataillon had issued a sua sponte ruling that certain pharmaceutical patent claims were invalid under 35 U.S.C. § 101 -- even though the defendant had not moved for such a ruling.  On appeal, the Federal Circuit has vacated and remanded -- "trusting" that on remand Judge Bataillon "will take an objective, measured, and thorough look into the legal issues and evidence of record to resolve only those disputes that exist between the parties."

Judge Bataillon's colorful opinion language asserted that the branded and generic pharma companies have colluded to pervert the intent of Hatch-Waxman.  On remand, it may be substantially drier.

Traditional Principles of Equity Acknowledge that Ongoing Infringement is an Irreparable Harm

Patent

by Dennis Crouch

The Supreme Court's landmark decision in eBay v. MercExchange dramatically changed the patent landscape by eliminating the potential of injunctive relief for many patent holders, even in the face of ongoing infringement. The Patent Act indicates that injunctions may be awarded "in accordance with the principles of equity," 35 U.S.C. 283, and in eBay, the Court found this required usage of a "four-factor test historically employed by courts of equity."  The central factor in the test for permanent relief is whether the infringement constitutes irreparable harm against the patent holder.  Prior to eBay, courts had seen infringement as indicative of irreparable harm, but altered their approach after eBay so that today a judgment of infringement comes with no presumption or indication that those tortious acts constitute irreparable harm.

A recently filed appeal before the Federal Circuit seeks to alter this new status quo -- particularly by providing an extensive historical analysis of how traditional courts of equity analyzed irreparable harm in the context of injunctive relief.  The new case is at the preliminary injunction stage, but the preliminary injunction test includes the same irreparable harm clause.

Teva v. Amneal: Orange Book Listing Requirements Under Scrutiny

Patent

by Dennis Crouch

The Federal Circuit is set to hear oral arguments in November 2024 in Teva v. Amneal, No. 24-1936, a case that could significantly impact Orange Book patent listing (and delisting) practices under the Hatch-Waxman Act (formally known as the Drug Price Competition and Patent Term Restoration Act of 1984).  Hatch-Waxman established a framework for generic drug approvals in the United States. It aims to balance incentives for pharmaceutical innovation with mechanisms to facilitate faster generic drug entry, including provisions for challenging patents listed in the FDA's Orange Book and offering a 180-day exclusivity incentive for first generic entrants.  The Orange Book listing also comes with a powerful 30-month stay -- pausing generic entry - if the patentee sues a generic seeking FDA approval.

At issue are five patents related to Teva's ProAir HFA (albuterol sulfate) Inhalation Aerosol, a metered dose inhaler (MDI) product. The patents claim various aspects of the inhaler device and dose counter, but do not expressly recite the active ingredient albuterol sulfate. Teva listed these patents in the FDA's Orange Book for ProAir HFA.  The big-money question in the case is whether these device patents are properly listed -- recognizing that the Orange Book is particularly for patents that claim either the drug or a method of using the drug.

The Enduring Impact of In re Keller on Obviousness Analysis

Patent

by Dennis Crouch

In 1981, the U.S. Court of Customs and Patent Appeals (CCPA) issued its decision in In re Keller, 642 F.2d 413 (CCPA 1981), a case that continues to shape obviousness determinations over four decades later. As the predecessor court to the Federal Circuit, the CCPA's rulings remain precedential and influential, with Keller cited 10,000+ times by the USPTO's Patent Trial and Appeal Board (PTAB) and its predecessor Board, the BPAI.

In the typical USPTO vs Applicant negotiation, Keller favors the USPTO and is often cited to uphold examiner rejections. Although the case remains influential, it does have some fundamental problems. Notably, it creates a gap -- what is not sufficient evidence -- and then fills that gap with the amorphous language of "suggestion." But this gap places the case in the good company of KSR v. Teleflex that similarly calls for flexibility in finding ways to judge obviousness.

Supreme Court’s Patent Docket: A Preview of the October 2024 Term

Patent

by Dennis Crouch

The Supreme Court's October 2024 term begins a day early this year. On September 30, the Court will meet for what has become known as the "long conference" -- passing judgment on dozens of petitions that have been briefed over the summer break.  The long conference is primarily a time to deny a large swath of petitions with very few certiorari grants.  Petitioners are usually simply hoping for a relist -- holding over their case for some future conference and a more complete consideration.

A number of patent cases will be reviewed that day.  The following are patent cases scheduled for the Long Conference, listed roughly in the decreasing order of likelihood of being granted certiorari (in my estimation):

“Directed to” vs. “Reciting” vs. “Involving” an Abstract Idea

Patent

by Dennis Crouch

I have been reading a good number of PTAB decisions recently to try to get my head wrapped around the current state of the obviousness and eligibility doctrines within the USPTO.  The Board's recent decision in Ex parte Annakov is on point.  The case involves a distributed service-and-transaction system for aircraft passengers, and the examiner rejected the claims both for lack of eligibility under § 101 (all the claims) and as obvious under § 103 (most of the claims).  On appeal, the Board reversed on eligibility, but affirmed on obviousness -- leaving a handful of claims ready for issuance.

If the Barcode Doesn’t Fit: Reconsidering ‘Bodily Incorporation’ in Patent Law

Patent

by Dennis Crouch

Many of us feel the daily pull toward coffee, and perhaps likewise toward PTAB decisions about coffee makers.

I found interesting a recent pair of IPR decisions successfully brought by the Swiss Nespresso against German competitor K-Fee.  This post delves into these cases and what I call the 'glove doesn't fit' fallacy in patent law obviousness doctrine; it also provides a discussion of how written description continues to be a risk, even in inter partes review (IPR) proceedings.

Federal Circuit’s New Hands-Off Approach: Recent Mandamus Denials Signal Shift in Venue Transfer Landscape

Patent

by Dennis Crouch

On September 11, 2024, the Federal Circuit issued three separate orders denying petitions for writs of mandamus related to venue transfer decisions. These cases highlight a trend that I previously recognized of the court stepping-back from its prior aggressive mandamus docket.  The cases here all include the similar procedural posture where the district court ordered transfer under the convenient venue statute 1404(a), and the patentee unsuccessfully petitioned the Federal Circuit to reverse the transfer.

Managing tipping payments is an administrative problem, not a technological problem

Patent, , , ,

by Dennis Crouch

This is the third eligibility post in as many days.  In a non-precedential decision issued September 10, 2024, the Federal Circuit affirmed the PTAB's rejection of claims in a patent application directed to eliciting tips for media content -- finding them ineligible. In re McDonald, No. 24-1015 (Fed. Cir. Sept. 10, 2024).

The applicant here is a Utah start-up VidAngel, Inc., that helps folks "Filter out the stuff you don’t want to see or hear in your streaming movies & TV shows, like profanity, nudity, violence & more.  But, the invention here has a different focus - it is a setup for eliciting and receiving tips from consumers of media content like streaming movies.

2nd Innovator Diversity Pilots Conference: Advancing Inclusion in Innovation

Patent

Coming up just before the big IPO conference in Chicago, Emory Law in Atlanta will be hosting the 2nd Innovator Diversity Pilots Conference.  This event looks excellent, and I wish I could attend. (I'll be in the woods at a "ManKind Project" retreat).

Details: Friday, September 20, 2024, 8:45 a.m. - 5:30 p.m.  In person or online. https://law.emory.edu/impact/conferences/innovator-diversity-pilots-conference.html.

USPTO Dir Kathi Vidal and other Biden Administration officials have been very open to trying well designed pilot programs that offer some promise to effectively increase participation and engagement of underrepresented groups within the innovation ecosphere.  Although many of the pilots focus on gender and race/ethnicity, the mindset of most really seems to be thinking about ways to make sure that everyone feels that patent-incentive -- adding fuel to the fire of genius.  I expect that the pilots that really work will be rolled-out as deliverables to everyone.

Key topics:

- Lessons learned from recent innovator diversity pilots
- Practical insights from the Diversity Pledge and other law firm diversity initiatives.
- The future of patent drafting and prosecution in the age of AI
- Strategies for retaining diverse talent in the patent profession

It is a mix of academic research presentations and practical discussions.

Future of Patent Practice: Balancing Big Firm Mergers and the Boutique Draw

Patent

by Dennis Crouch

I saw this morning that Womble Bond Dickinson and Lewis Roca are merging to create firm with 1,300+ lawyers. By my quick count, the new combo will have 150+ US patent attorneys under the WBD brand that the wider-known of the two (especially internationally).  Two other big mergers announced this week - Troutman Pepper and Locke Lord; Ballard Spahr and Lane Powell.   The "Troutman Pepper Locke" merger will result in 1,600+ lawyers, with about 200 lawyers in their IP group (of which about 100 will be "patent attorneys").   The Ballard Spahr merger is also large (750+ lawyers), but Lane Powell's IP practice is fairly small -- likely meaning that Ballard Spahr's patent group (largely based in Atlanta) may end up quite successful if they are able to cross-sell to Lane Powell's clients.

Drafting for Eligibility: Insights from the Federal Circuit’s Contour IP v. GoPro

Patent, , ,

by Dennis Crouch

In Contour IP v. GoPro, the Federal Circuit has reversed a Judge Orrick (N.D.Cal.) summary judgment of ineligibility.  The case here should be one for patent drafters  to consider -- particularly thinking about how to incorporate specific technological improvements into their patent claims and specification (while still maintaining broad claim coverage).  Of course, the patentee here has the benefit of actual hardware beyond mere processing.

Contour owns two patents related to POV video cameras. These patents claim a camera system having lenses, sensors, etc., that generates two video streams of different quality in parallel, wirelessly transmitting the lower-quality stream to a remote device for real-time viewing and control on your phone. The higher-quality stream is stored on the camera for later use.

The Patent Eligibility Restoration Act (PERA) of 2024: From Oz to Earth

Patent, , , , ,

by Dennis Crouch

As its name suggests, the Patent Eligibility Restoration Act (PERA) is designed to substantially overturn the Supreme Court's decisions in Mayo Collaborative Services v. Prometheus Laboratories, Inc., 566 U.S. 66 (2012), and Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014). Together those cases created a firestorm of invalid patents and challenges for the patent office and patent holders alike.  The bipartisan proposal was introduced in the Senate (Coons/Tillis) earlier this term and most recently introduced to the US House of Representatives (Kiley/Peters).   Although Alice and Mayo doctrine created substantial confusion, much of that confusion has now died down in the past decade.* The bigger issue is that it is substantially harder to obtain patents and easier to invalidate issued patents -- particularly in cases where the invention lies in software or diagnostic methods.  This post examines the proposed PERA and its potential impact -- along with providing a bit of data.

* Although the extreme confusion is gone, there is still plenty to go around.  A case in point is the Federal Circuit's September 3, 2024 decision in BBiTV v. Amazon. In that case, the court showed its linguistic flexibility in distinguishing the claimed user interface (deemed ineligible) from those in Core Wireless and Data Engine (deemed eligible).

Thorn in USPTO’s Side: Judge Fitzpatrick’s Whistleblower Victory

Patent, , , , ,

by Dennis Crouch

In a significant ruling, the Merit Systems Protection Board (MSPB) granted corrective action to PTAB Administrative Patent Judge (APJ) Michael Fitzpatrick in his whistleblower retaliation case against the USPTO associated with his complaints about PTAB panel expansion (i.e., 'panel stacking').  The decision issued back in 2023, but has only just now been published following a settlement between Fitzpatrick and the USPTO.  This post will delve into the details of Fitzpatrick's claims, the MSPB's reasoning, and the implications of this decision for patent practitioners and the USPTO.

Hindsight 20/20: Federal Circuit Okays Retroactive Expertise

Patent, , , , ,

by Dennis Crouch

In patent litigation, we continue to see enhanced focus on qualifying (i.e., disqualifying) expert witnesses. Skilled expert testimony can be so convincing for a jury while also laying the foundation to win on appeal.  And, expert testimony is a legal necessity in most patent cases both for damages calculations (damages expert) as well as for validity and infringement (technical expert).  Having your expert knocked-out just before or in the midst of trial is a nightmare situation.

In its 2022 Kyocera decision, the Federal Circuit explained that a technical expert must - at minimum - be a person of skill in the art to which the invention pertains.  Someone who purports to be an expert but lacks that 'ordinary' knowledge will be disqualified under patent law's Daubert nuance.  In patent law, PHOSITA's knowledge is temporally tied to the patent application filing date (or invention date pre-AIA).  What we're typically looking for is the level of skill at the time that the application was filed (or perhaps when issued / amended).

This temporal frame is the focus of the Federal Circuit's recent decision in Osseo Imaging v. Planmeca, where the court was asked to disqualify the patentee's expert witness because he was not skilled in the art back when the invention was made -- rather, became skilled almost a decade later.

The case has some parallels to EcoFactor v. Google, that is currently pending before the Federal Circuit on an en banc petition regarding admissibility of damages expert testimony.

From Knobs to Pixels: UI Patent Eligibility on Trial

Patent, , , , ,

by Dennis Crouch

For over 150 years, "user interfaces" have been a staple of patent protection, evolving from the physical realm of tool handles and knobs to today's digital screens. Although tangible interface elements continue be patented as components of larger systems, the market shift towards on-screen interfaces has been paralleled with the anti-eligibility shift in Mayo and Alice. The Federal Circuit recently waded into these murky waters in Broadband iTV, Inc. v. Amazon.com, Inc., No. 23-1107 (Fed. Cir. Sept. 3, 2024), examining the patent eligibility of electronic programming guides and content recommendation systems. Affirming a decision by Judge Albright, the appellate panel held that the claimed inventions lacked eligibility under 35 U.S.C. § 101, distinguishing some prior GUI cases that sided with the patentee.

Did Jarkesy Undermine Oil States? ParkerVision Thinks So

Patent, , , ,

by Dennis Crouch

In 2018, the Supreme Court's 7-2 decision in Oil States Energy Services, LLC v. Greene's Energy Group, LLC, 584 U.S. 325 (2018) affirmed the constitutionality of inter partes review (IPR) proceedings. The Court held that patents are "public rights" and thus may be canceled through congressionally authorized administrative proceedings without violating Article III or the Seventh Amendment right to a jury trial. This decision was a significant win for proponents of the America Invents Act (AIA) and those seeking to use the Patent Trial and Appeal Board (PTAB) as an efficient mechanism to cancel issued patents.

Fast forward to 2024, and a number of us were watching the non-patent case of SEC v. Jarkesy, 144 S. Ct. 2117 (2024), wondering if it might destabilize Oil States. Jarkesy indeed narrowed the scope of what qualifies as a "public right," potentially reopening the debate on the constitutionality of IPRs.

Tapping our Full Potential: Nominations for US Council on Inclusive Innovation

Patent

by Dennis Crouch

A cornerstone of Dir. Kathi Vidal's tenure as USPTO Director has been a continued focus on inclusivity and diversity in the innovation ecosphere.  In 2024, the USPTO launched a significant initiative to address major disparities in patent participation among underrepresented groups -- with strong support from the Council for Inclusive Innovation (CI2).  CI2 is now seeking nominations for new council members. In addition to highlighting the nomination process, this post provides some critiques on the initiative's approach to fostering a more diverse and dynamic innovation landscape in the United States.

The Art of Losing Gracefully or How Koki’s appellate loss is truly a win.

Patent, , , , , ,

by Dennis Crouch

We have seen lots of ITC action recently. In the new Koki v. ITC decision, the Federal Circuit found that the accused infringer Koki lacked Constitutional standing to bring the appeal  based upon a binding promise not to sue submitted by the patentee Kyocera.

As I discuss at the end of this post, although Koki is the nominal loser, the company substantially advanced its position on appeal because Kyocera was forced to declare (and then clarify) its promise in order to obtain dismissal.

Omitted Elements and Written Description: Federal Circuit’s Split Decision in Allergan v. Sun Pharma

Patent, , , , , ,

by Dennis Crouch

I previously wrote about Allergan USA, Inc. v. MSN Laboratories Private Ltd. (Sun Pharma), No. 24-1061 (Fed. Cir. Aug. 13, 2024), focusing on Federal Circuit's about-face on obviousness-type double patenting.  My original post skipped over an important aspect of the opinion: the court's 2-1 decision favoring the patentee on the written description requirement of 35 U.S.C. § 112(a).  This portion of the case focuses once again on when an element is "essential" to the invention and therefore required in the claims.

Four key takeaways:

  1. We presume that no element is "essential."
  2. Courts should look for indications in the patent documents that the feature is critical, essential, etc.
  3. The court here relied upon broad claims in the priority filing that were later deleted in order to show the inventor possessed embodiments that did not require the element.
  4. The key focus for written description is comparing the specification with the claims.  Although expert testimony may be relevant, it must be directly tied to the intrinsic record.

All of these elements point to the idea that it is the job of the patent drafter and prosecutor to ensure the written description is sufficient, and to avoid pitfalls that might indicate otherwise.
