Vanda v. Roxane Labs. – Are Two Natural Laws Better Than One?

Monday, September 26th, 2016

iStock_000007770475_SmallAs you will recall, in Prometheus v. Mayo, the Supreme Court held that a claim reciting a natural law had to have other non-conventional steps to pass muster under s. 101. The natural law in Mayo was the correlation between the concentration of the metabolite of the immunosuppressive drug and the efficacy of the drug – unpleasant side effects at the high end of the recited range and lack of efficacy at the low end. The Mayo Court wrote: “We need not, and do not, decide whether were the steps at issue here less conventional, these features of the claims [the administering, determining and recognition steps] would prove sufficient to invalidate them.” It was unnerving that the invalidated claims were method-of-treatment claims.

In his opinion in a Hatch-Waxman litigation involving the anti-schizophrenia drug Iloperidone, Vanda Pharms., Inc. v. Roxane Labs., Inc., Civil Action No. 13-1973-GMS; 14-757-GMS (D.Del., 2016), Judge Sleet upheld the validity  of the compound and the method claims in Reissue Patent No. 39,198 and US Patent No. 8,586,610.

Apotex v Wyeth Explores Structural Obviousness

Thursday, September 1st, 2016

Lately, I’ve been feeling that the only case law engaging enough to write about has involved S. 101 issues, so it was a welcome break to comment on some classic principles of organic chemistry.

iStock_000002291402Small(2)Apotex filed an IPR petition that Wyeth’s U.S. Patent No. 8,879,828 was obvious in view of four references. The Board granted the petition but went on to find that the antibiotic compositions claimed in the patent were not obvious. The Fed. Cir. agreed that the Board’s final decision was supported by substantial evidence  (Appeal No.  2015-1851 (Fed. Cir., August 6, 2016)  —Judges Lourie, Wallach and Hughes, Lourie writing).


Arendi S.A.R.L. v. Apple, Inc. – Defining “Common Sense”

Monday, August 22nd, 2016

For some time, I have wanted to do a post on this recent Fed. Cir. decision (Appeal No. 2015-2073 (Fed. Cir. , August 10,  2016),) in which the Fed. Cir. panel of Judges Moore, Linn and O’Malley (writing) reversed a PTAB decision finding most of the claims of U.S. Patent No. 7,917,843 obvious over a single prior art reference, U.S. Patent .No. 5,859,636 (“Pandit”). Claim 1 is more than a page long, and I will not try to describe it in any detail, except to say that it can be exemplified by the use of a computer program to build an address book.


Limelight Networks v. Akamai Tech. – Cert. Denied

Monday, April 18th, 2016

Today the Supreme Court declined to hear Limelight’s petition for cert. on the question of whether an accused infringer may be held liable for direct infringement of a claim to a method where multiple parties perform the steps of the method.

On August 13, 2016, the S. Ct. remanded the en banc decision of the Fed. Cir. that set forth the law of divided infringement under s. 271(a), and found that Limelight directly infringed U.S. Pat. No. 6,108,703. The court held that an entity will be found responsible for others’ performance of method steps “(1) where that entity directs or controls others’ performance, [or] (2) where the actors form a joint enterprise.”  (more…)
