Written Description and Creating Ranges from Examples

April 7, 2022

At the close of last year, the Federal Circuit affirmed a decision by the PTAB in IPR2019-00329 that a claimed range created from examples was not patentable because it lacked written description in the application as filed. In its decision the PTAB “second guessed” an examiner’s ex Parte decision that the claimed range had written description in the application as filed.  Written description was at issue because the patent challenged, U.S. Patent 9,687,454 (‘454), filed January 6, 2016, needed benefit of its parent application serial number 12/537,571 published on February 10, 2011, as 2011/0033541 (‘541), to avoid ‘541 from being prior art otherwise, most of the ‘454 claims were anticipated by ‘541. The ‘454 claim 1 is directed to a mucoadhesive film comprising about 40 wt.% to about 60 wt.% of a water-soluble polymeric matrix and claim 7 to a range of from about 48.2 wt.% to about 58.6 wt.%. Neither range was found in the ‘454 patent as filed; the claims were added during prosecution. The ‘454 describes the film as “may contain any desired level of self-supporting film forming polymer”; in “one embodiment, the film forming composition” may be at least 25 weight per cent of the composition; alternatively, at least 50 weight per cent of the composition. No upper limit was described.<... Read more

Patent Invalidation Under Section102(b)'s On-Sale Bar Based on a Letter Including Commercial Terms Sent Before the Critical Date

March 28, 2022

Mr. Junker, the named inventor of U.S. Design Patent No. D450,839, sued Medical Components, Inc. and Martech Medical Products, Inc. (“MedComp”) for infringement of the D’839 patent. The parties filed cross-motions for summary judgment, debating whether a letter sent before the critical date was a commercial offer for sale of the claimed design, rendering the claim invalid under the on-sale bar, 35 U.S.C. § 102(b). The district court granted Mr. Junker’s motion for summary judgment of no invalidity under the on-sale bar. MedComp appeals the district court’s summary judgment of no invalidity under the on-sale bar, the judgment of infringement, and the damages award.<... Read more

December 27, 2021

Following up on my post last week (Dec 1.), I have read commentary about how the Federal Circuit’s decision in Biogen v. Mylan was incorrect. Is it really the case that the decision was wrong and that the Federal Circuit needs to address it en banc (or that the Supreme Court needs to address it)? <... Read more
