Sequenom Files Petition for Cert. After Invalidation of Cff Patent

Tuesday, March 22nd, 2016

supreme-courtSequenom, the loser in “Ariosa,” has filed a petition seeking Supreme Court review of the Fed. Cir.’s invalidation of the claims of US Pat. No. 6,258,540 as an attempt to claim a natural product, cffDNA. While there is no dispute among the commentators that this decision was flat-out wrong, the majority of the panel seemed to agree that it was compelled by the “Mayo/Alice Rule” (after they spotted the natural product, cffDNA, and ignored the other claim steps as conventional). (A copy of the Petition can be found at the end of this post.)

As previously noted by me, this is not a great case to settle the issue of whether or not claims based on biomarkers are patent-eligible. All of the claims on appeal, except for claim 21, are simply directed to methods for detecting cffDNA in a maternal serum or plasma sample. These claims are as patentable as a method of testing transgenic potatoes for the level of the precursor to acrylamide – a carcinogen that you do not want in your chips. The claim is a method claim, even if the precursor enzyme is a natural product. Even the ACLU in Myriad argued that, while a new method of mining gold would be patentable subject matter, a gold nugget is not.

Ohio Willow Wood’s Appeal of IC Finding Goes Up In Smoke

Tuesday, February 23rd, 2016

iStock_000062460636_SmallOn February 19th, the Fed. Cir. affirmed a District Court’s finding of inequitable conduct in Ohio Willow Wood Co. (OWW) v. Alps South (Alps), LLC, following the Fed. Cir.’s remand of summary judgment of no inequitable conduct in 2013. (Ohio Willow Wood Cr. v. Alps South LLC, 2015 U.S. App LEXIS 2864 (Fed. Cir. 2016).) (A copy is available at the end of this post.)

The facts of the case are complex, and involve two reexaminations of U.S. Pat. No. 5,830,237, claiming a cushioning device for amputees, “SSGL.”

Therasense Puts A World Of (Antitrust) Hurt On 3M

Wednesday, February 17th, 2016

iStock_000000232341_SmallCommentators who have declared inequitable conduct dead and buried should study TransWeb, LLC v. 3M Innovative Properties Co., App. No. 2014-1646 (Fed. Cir., Feb. 10 2016). {A copy can be found at the end of this post.] The decision demonstrates how the “but-for materiality” and specific intent standards of the Therasense decision can open the door to Walker Process liability for antitrust violations and the award of trebled fees and damages.

In this case, 3M had sued TransWeb for patent infringement of several patents on non-woven, fluorinated fabrics used in respirator masks. The patents were invalidated due to 3M’s failure to disclose that it had obtained samples of the fabric from TransWeb, that had given away samples at a trade show more than a year prior to the effective filing date of the patents. There is a thorough analysis of the facts surrounding 3M’s obtention of the samples, but the Fed. Cir. found that the weight of the evidence corroborated the testimony of the TransWeb founder, that he had given out samples of the claimed product. This was enough to invalidate the 3M patents under the public use bar.
