Dispensing Claim Construction

Ventana Medical Systems sued BioGenex Labs for infringing 6,352,861, which claimed automated staining of microscope slides. The asserted stain didn't take well in claim construction: the district court found non-infringement based on a narrow construction disclosed throughout the patent and in prosecution history. By 2-1, the CAFC majority used a different microscope (CAFC 06-1074), though the dissent concurred with the district court decision. Here, in a turnabout from previous rulings, where claims would not be construed broader than the disclosed embodiments, or broader than envisioned by the inventors, the appeals court muddies the tenets of claim construction.

Sloppy Assertion

Engate asserted its court reporting patents, and in doing so, showed that clown time is not over at the courthouse. Atkinson-Baker & Esquire, defendants in the case, got summary judgment of "what was the plaintiff thinking?!" Ditto on appeal (CAFC 06-1140), and then some.

Generic Anticipation

Generic drug makers IVAX Pharmaceuticals, Dr. Reddy's Laboratories, and Teva Pharmaceuticals filed an ANDA for the patented drug olznapine, used to treat schizophrenia. So, naturally, patent owner Eli Lilly sued for infringing 5,229,382. In a 221-page analysis following a 2.5 week bench trial, '382 was found valid and infringed. In a last hurrah, the generic defendants appealed, arguing one last time invalidity and inequitable conduct (CAFC 05-1396).

Texas Smart

District judges in Texas smell a new crude that looks profitable: patent litigation. Judge Ward in the Eastern District penned rules that made that district seem the patent litigation capital of the U.S. Now other Texas districts are making a draw from the same deck.

On-Sale Bar Kiosk

Plumtree Software sought, and got, a declaratory judgment against Datamize, convincing a district court to summary judgment invalidity under the on-sale bar doctrine, 35 U.S.C. § 102(b), killing 6,460,040 and 6,658,418, continuations of 6,014,137. Two issues on appeal (CAFC 06-1017): whether Plumtree had "reasonable aprehension" to file for declaratory judgment, and whether the on-sale bar doctrine had been met.

Shields Up

Things are running hot between L&W and Shertech, manufacturers of heat shields for autos. Starting the fracas, L&W sought declaratory judgment of non-infringement against Shertech's 5,670,264, also arguing invalidity and inequitable conduct unenforceability. Shertech naturally counterclaimed infringement, which the district court granted in summary judgment. Then a jury trial on invalidity, where only claim 7 survived.

DSU Medical sued Japanese medical supply company JMS and SE Asian manufacturer ITL for direct, inducement, and contributory infringement of 5,112,311 and 5,266,072, which claim a guarded winged-needle device that reduces the risk of getting stuck with the needle. The defendants avoided getting stuck with claims 46-47 and 50-52 of '311 by proving invalidity, but JMS got jabbed $5 million for infringing '311 claims 49, 53-54. Though long-winded in doing so, the CAFC (04-1620) wholly concurred with the trial court.

Patent Search Engines

There are a few free patent search engines available. Google, having kept the scanning gnomes up past bedtime, has all issued U.S. patents since Columbus was found to be infringing. There are also FreePatentsOnline and PatentReader, as well as the venerable USPTO search. Not exactly fun entertainment for the whole family, nor particularly industrial-strength.

Anonymous Dog Eats Homework

The Medicines Company filed papers today with the SEC blaming its outside legal counsel for being one day tardy in filing for a patent extension for its blockbuster anti-blood clotting drug Angiomax.

Injunction Kabuki

Sanofi markets Plavix®, used for heart attacks and strokes, and covered by 4,847,365. Maneuvering by the Hatch-Waxman Act playbook, Apotex filed an ANDA for a generic version, triggering an infringement suit by Sanofi. Apotex counterclaimed with invalidity. In due time, the FDA approved the ANDA. Sanofi and Apotex settled... well, except that government regulators, the FTC and state attorney generals, nixed the settlement as not copasetic.

Ottawa-based Wi-LAN got a "way-to-go!" on the Toronto Stock Exchange after scoring a patent coup from Nokia; Wi-LAN's share price jumping 64% on the news, to $4.40 Canadian.
