Eye Therapies, LLC. v. Slayback Pharma, LLC: How Prosecution History Can Alter Phrase Interpretation

Attorney: David Inglefield
July 23, 2025

On June 30, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision regarding transitional phrase claim construction, reversing the decision of the Patent Trial and Appeal Board (PTAB) in Eye Therapies, LLC. v. Slayback Pharma, LLC. The PTAB had previously ruled the claims of U.S. Patent No. 8,293,742 (the ‘742 patent) unpatentable as obvious in a inter partes review brought by Slayback. During the inter partes review, the parties had disagreed on the construction of the transitional phrase “consisting essentially of” in the ‘742 patent. The Court found that the Board had incorrectly applied the conventional open construction of the transitional phrase, which was at odds with the prosecution record. This demonstrates how prosecution history can alter a phrase’s typical meaning.<... Read more

Attorney: David Inglefield
March 10, 2025

On February 13, the U.S. Court of Appeals for the Federal Circuit (CAFC) reversed the decision of the International Trade Commission (ITC) in US Synthetic Corp. v. International Trade Commission, issuing a precedential decision regarding subject matter eligibility important to the pharmaceutical and other life science industries. The ITC had previously ruled that US Synthetic’s composition of matter claims reciting measured properties of a composition were directed to a patent-ineligible abstract idea under 35 U.S.C. § 101. The CAFC found that the claims were indeed related to concrete structures, not patent-ineligible abstract ideas, and affirmed the lower court’s finding regarding enablement.<... Read more

Patenting of Multi-Disciplinary Subject Matter – Personalized Medicine

Attorney: Robert W. Downs
February 7, 2025

Personalized medicine is especially intriguing, as a problem with most drugs are the potential side effects. From a naive perspective, administering drugs may appear to be a trial and error process:  take this for two weeks and come back with a follow up visit.  If you have any side effects, contact me immediately.  Wouldn’t it be nice if a drug had the effect it was meant to have without the possibility of side effects?<...

Myrbetriq® Patent Invalidated On Grounds Not Asserted by Any Party Violating Party Presentation Principle

Attorney: Richard D. Kelly
October 2, 2024

In Astellas Pharma Inc. v. Sandoz Inc,, et al, following a five-day patent claims bench trial the court found asserted claims 5, 20, and 25 invalid under 35 U.S.C. § 101 even though Sandoz had not asserted 101 as defense at any time during the case.  The parties had agreed to limit the issue to claims 5, 20, and 25 and the defense to invalidity under 35 U.S.C. § 112.  Neither party had notice that patent eligibility was an issue.  In making his ruling Judge Bataillon relied upon a statement in Astellas post-trial brief that the “inventive concept of the ’780 Patent was discovering the dissolution rate that would address the food effect and achieving it using previously known formulation technology.”  Thus, because the claimed invention “reflects merely the discovery of the food-effect-resolving dissolution profile,” the district court deemed the asserted claims invalid as patent ineligible.  Not only had the issue of patent eligibility not been raised by the defendant, but the claims were also to a specific composition.  Recognizing the district court had gone on astray Sandoz moved the court to make additional findings of fact  advising the court that the § 101 defense had not been raised as a defense and that the decision must be based on the language in the claims.  The motion was denied.<...

Attorney: Richard D. Kelly
August 28, 2024

In Allergan USA, Inc v Sun Pharmaceutical Indus. Ltd, Appeal No. 2024-1061, August 13, 2024, the Federal Circuit reversed the district court’s holding that Allergan patent, U.S.P. 7,741,356 (‘356) was invalid for obviousness-type double patenting over USPs 11,007,179, 11,090,291, and 11,311,516. The relationship between the patents is shown below:


The ‘356 patent was entitled to significant PTA but because of the PTE it received, Allergan effectively disclaimed all but 487 days of the PTA. The total extension PTE plus PTA resulted in an expiration date of May 27, 2029, 15 years from the ‘356 issue date -- the maximum extension possible.<... Read more
