Double Patenting and Patent Term Adjustment

Patent, , ,

by Dennis Crouch

The Federal Circuit recently issued an important decision in In re: Cellect, LLC (Fed. Cir. Aug. 28, 2023) regarding how Patent Term Adjustment (PTA) interacts with terminal disclaimers and obviousness-type double patenting (ODP). This case establishes binding precedent that a terminal disclaimer cuts off any extended patent term granted through PTA.

This holding contrasts with the court's prior rulings regarding Patent Term Extension (PTE), where the extended term is calculated from the disclaimed expiration date, not the original expiration date. Thus, PTE extends beyond a disclaimed term, while PTA does not.

This result was expected by many patent experts, although some in the pharmaceutical industry had pushed for PTA to extend beyond disclaimed terms similarly to PTE. In the end, the statutory language expressly addressing disclaimers in the context of PTA proved decisive. This precedent will apply to all patents already in-force as well as those issued in the future.  Thus, applicants will want to carefully consider PTA and terminal disclaimer strategy for patent families.

9th Circuit Revives False Claims Act Action for Fraud on the Patent Office

Patent,

by Dennis Crouch

The U.S. Court of Appeals for the Ninth Circuit recently issued a pair of decisions in the qui tam case Silbersher v. Valeant Pharmaceuticals concerning the False Claims Act's (FCA) public disclosure bar.  The case sets significant precedent in linking FCA claims to patent prosecution and fraud upon the patent office.  The case can be contrasted with Silbersher v. Allergan, Inc., 21-15420, — F.4th — (9th Cir. Aug. 25, 2022) [21-15420], that Silbersher lost.

“Bald Girls Do Lunch” Unable to Sway the Federal Circuit in Case Involving Deuterated Drug for Alopecia Areata

Patent,

By Chris Holman

Sun Pharmaceutical v. Incyte, 2023 WL 5370639, Not Reported in Fed. Rptr. (Fed. Cir. Aug. 22, 2023)

Bald Girls Do Lunch (“BDGL”) is a nonprofit organization dedicated to improving the quality of life for females living with alopecia areata (“AA”).  AA has been described as “an autoimmune skin disease resulting in partial to complete hair loss on all hair-bearing areas of the body, including, for example, on the face, resulting in loss of eyebrows and eyelashes.” According to BDGL, “AA is not a simple cosmetic problem—it is a chronic, often devastating condition that has substantial and wideranging implications, affecting patient’s physical, mental, and emotional health.  Indeed, in severe cases, AA can lead to chronic depression.”

Third Circuit Allows Deduction of Generic Hatch-Waxman Defense Costs

Patent

by Dennis Crouch

Mylan v. IRS, No. 22-1193, --- F.4th --- (3d Cir. July 27, 2023)

In a recent tax appeal, the Third Circuit court of appeals afformed that legal expenses incurred by generic drug makers to defend against patent infringement suits brought under the Hatch-Waxman Act are deductible as ordinary and necessary business expenses. This aligns with longstanding precedent treating patent litigation defense costs as deductible for the alleged infringer.

PTAB Captains Take Notice: Carefully Weigh Secondary Considerations

Patent,

By Dennis Crouch

The nexus requirement serves as a threshold that must be met before secondary indicia will be even considered as relevant to the obviousness inquiry.  In its recent Volva Penta decision, the Federal Circuit found that the PTAB had  (1) created too high of a burden to prove nexus and (2) been unduly dismissive of the patentee's evidence of commercial success and copying.  The case reinforces the notion that patentees should attempt to include some claims that are largely coexistive with its product line, especially in today's world of likely copying. The case also serves as a reminder that product copying still caries significant weight in the obviousness analysis. Volvo Penta of the Americas, LLC v. Brunswick Corp., 22-1765, --- F.4th --- (Fed. Cir. August 24, 2022).

Aseptic Patent Law: Which Side of Literal do you Favor?

Patent

by Dennis Crouch

Steuben Food recently lost its infringement case against Shibuya Hoppmann with the district court holding (1) the doctrine of equivalents (DOE) cannot extend to cover the accused aseptic bottle filling technique and further (2) the reverse doctrine of equivalents shields the defendant against charges of literal infringement.  Steuben Foods, Inc. v. Shibuya Hoppmann Corp., No. 1:19-cv-02181-CFC, 2023 WL 2498810 (D. Del. Mar. 14, 2023) (U.S. Patent Nos. 6,209,591; 6,536,188; and 6,702,985) (Chief Judge Connolly). The case is now pending on appeal at the Federal Circuit with the successful defendant's responsive brief due in mid-September.

Looking Back: Graver Tank after 70 years

Patent

by Dennis Crouch

The Supreme Court's landmark 1950 decision in Graver Tank & Mfg. Co. v. Linde Air Products Co., 339 U.S. 605 (1950) is one of the court's most cited patent cases.  The decision established important guideposts for applying the doctrine of equivalents ("DOE"), including consideration of the prior art and a focus on the substantiality of differences. While courts today emphasize evaluating equivalence on an element-by-element basis, Graver Tank's substantive analysis remains highly influential.

Three issues: Law/Fact Distinction in Obviousness; Envisaging the Invention; and Newman in Dissent

Patent,

by Dennis Crouch

Incept LLC v. Palette Life Sciences, Inc., No. 21-2063 (Fed. Cir. Aug. 16, 2023) (Majority by Judges Schall and Taranto; Dissent-in-part by Judge Newman)

The most interesting line in the case for appellate attorneys (and legal scholars) is probably the court's law/fact distinction in the context of obviousness analysis.  The majority wrote: "We see no reversible error ... whether viewed as a factual one about the level of [commercial] success or a legal one about the weight of any such success in the overall obviousness analysis."  The law/fact divide is important because of the evidentiary requirements in the first instance and the standard for review on appeal. Here, the court makes clear that the weight given to any objective indicia of non-obviousness is a question of law rather than a question of fact.  The result then is that its analysis can generally be based upon reason rather than evidence, and that issue is one that will be heard de novo on appeal.

New Amendment to FRCP Could Help Streamline Privilege Management in Patent Cases

Patent

by Dennis Crouch

On August 15, 2023, the Judicial Conference Advisory Committee on Civil Rules published proposed amendments to Rules 16 and 26 of the Federal Rules of Civil Procedure. One of the goals of these amendments is to encourage parties to address issues relating to claims of privilege and work product protection early in litigation. This could be particularly impactful for patent cases, which frequently involve extensive disputes over these very issues.  The proposal would also retitle Rule 16(b) to include both scheduling and case management (the current version just focuses on scheduling).

Meta Claim Construction: Finding Meaning in the Meaning

Patent,

by Dennis Crouch

One-E-Way, Inc. v. Apple Inc., 22-2020 (Fed. Cir. Aug. 14, 2023) (nonprecedential) (Opinion by Chief Judge Moore, joined by Judges Lourie and Stoll).

The district court sided with Apple on summary judgment, finding no infringement. On appeal, the Federal Circuit has affirmed, holding that Apple's accused Bluetooth products do not infringe One-E-Way's patents.  Although the parties had agreed to the construction of the "unique user code" term, they disagreed over the construction-of-the-construction.  On appeal, the court treated this meta-construction effectively as a form of claim construction -- looking for the ordinary meaning rather than a contract-like interpretation that would have looked more toward discerning the intent of the parties.

ApoA1-Fc Fusion Proteins: Federal Circuit keeps Patent Hopes Alive, Holding that the USPTO Must Explain its Decisions

Patent, ,

In re Theripion, Inc., 2022-1346 (Fed. Cir. Aug. 10, 2023) (nonprecedential) (Opinion by Judge Stark, joined by Judges Hughes and Cunningham).

ApoA1 is a key component of HDL, also known as "good cholesterol." The founders of Therapin created a synthetic "fusion protean" of ApoA1 linked to the Fc portion of an antibody (the stem).  That fusion extends the half-life of injected HDL and allows it to be a better potential drug treatment. The claims require a specific linker protein of 10-40 amino acids between the ApoA1 and Fc portions. Theripion discovered that this longer linker improved cholesterol efflux activity compared to fusion proteins having shorter 2 amino acid linkers or no linker.  So the essence of the invention as claimed is an ApoA1-Fc fusion protein with an optimized 10-40 amino acid linker that enhances the fusion protein's ability to remove cholesterol from cells as compared to a much shorter or absent amino acid linker.  To be clear, the prior art (including some work by the inventors here) had created ApoA1-Fc fusions, but with a short linkage. And, various types of connectors of the claimed length were also known.
