Wrong Temperature

Sensitech is exclusive licensee of RE36,200; Donald W. Berrian, inventor. Sensitech sued Time 'N Temperature (TNT) for infringement of '200. On summary judgment, the district court found the patent valid, and infringed, and placed an injunction on TNT. The appeals court readily ruled that was wrong (CAFC 06-1404).

Thai Patent Snatch

Thailand has pulled the plug on patent protection for two drugs: Plavix, a blood-thinner, and Kaletra, a "second-line" treatment for HIV/AIDS. The move is not against World Trade Organization rules, called TRIPS, which allow a government to unilaterally declare a public health crisis and peddle patented drugs under compulsory license. Naturally, the drug companies are howling.

Wooden Claim Construction

Anderson sued Fiber Composites, both composite wood makers, for infringing six patents in two groups. At the district level, claim construction split the difference in decision. Both parties appealed (CAFC 05-1434). The core issue was whether the process to make a product could be read into the claims. In this case, the CAFC observed, prosecution estoppel narrowed construction: "An applicant’s argument that a prior art reference is distinguishable on a particular ground can serve as a disclaimer of claim scope even if the applicant distinguishes the reference on other grounds as well."

Terminal Disclaimer & Extension

Merck owns 4,797,413, a CIP of a CIP of a CIP, terminally disclaimed at the end of June, 2004, but granted a three-and-a-half year extension by the USPTO because it took the FDA almost six years to okay Merck's dorzolamide (trade name: Trusopt), the drug for glaucoma treatment claimed by the patent. Merck claims the extension rides on the tail of the terminal disclaimer, extending the patent to the end of 2007. Hi-Tech Pharmaceutical wants to market a generic version, and says there is no tail to a terminal disclaimer, at least in this instance. A New Jersey district court ruling favored Merck; a ruling Hi-Tech appealed. No appeals court decision yet, but the murky intersection between terminal disclaimer and patent extension may be plowed clear as a result.

Disjointed Venture

Canon began SED TV technology research in 1986. In 1999, Canon took a patent license from Nano-Proprietary for its SED TV technologies. Canon then entered a joint venture with Toshiba in 2004 to develop this new type of flat-panel display. In doing so, it seems to have run afoul of its licensing agreement. Nano-Proprietary sued.

Not A Card

E-Pass shot blanks in asserting 5,276,311, which claims a method of replacing a bunch of credit cards with a single "multi-function card", against the makers of Palm PDAs and VISA. Following a narrow claim construction from the district court, E-Pass appealed, with the original district court ruling vacated by the CAFC. Next round: summary judgment of non-infringement by the district court on a slightly broader claim construction. So E-Pass appealed again (CAFC 2006-1356, -1357, -1358).

Having It Both Ways

MedImmune took a patent license from Genentech to make and sell its cash cow drug Synagis, used to prevent a respiratory tract disease in the very young. When faced with the perceived prospect of having to pay more royalties for a follow-on Genetech patent, MedImmune bolted - stopped paying fees, and sued for declaratory judgment of invalidity. The case headed north, to the Supreme Court, as the lower courts wouldn't touch it, because, the lower courts ruled, a licensee can't wiggle out by acting scared. In a narrow 8-1 holding, the Supreme Court ruled that a licensee may seek declaratory judgment of patent invalidity without breaching its licensing obligations.

Say Cheese

Back in March 2004, Kodak sued Sony for patent infringement of digital imaging technologies. Sony duly replied with its own ten-patent counterclaim. They then upped the ante with 24 Sony patents and 7 Kodak patents, for things like printers and film development. Folks couldn't keep track of the score, even reputedly changing the channel to snappy dance competitions. Faced with dropping ratings, the series was threatened with cancellation. So they gave it a happy ending by settling at the end of the year in a cross-licensing deal, with a bit of royalty to Kodak.
