Patent Pools

As a grant of monopoly power, patents have long been legally associated with antitrust. Using patents in an anticompetitive manner is patent misuse, and provides a defense to infringers. But is a patent pool, which may combine patents of related technology under a single license, ipso facto anticompetitive? In the case of Phillips v. The International Trade Commission, the CAFC (04-1361) didn't think so.

What can you do?

Every now and then I get a call from an independent inventor with a valid, issued utility patent who feels that his patent is being infringed. Upon review of the patent, file history and scrutiny of unlicensed products for sale in retail settings, a prima facia case of infringement can be made.

What can be done? I'd like to open a discussion.

Of course, cease and desist, followed by infringment lawsuit. But the economic realities often preclude an all out confrontation. Typically, all the client wants is a fair royalty payment....

Prepaid Grief

The Wall Street Journal has a picturesque story of the patent business in action, under the understatedly quaint heading: "Aggressive Patent Litigants Pose Growing Threat to Big Business". In making that headline statement, one can only surmise that the Wall Street Journal hasn't been paying attention to the patent game for the past 200 years or so.

Network Commerce sued Microsoft for infringing 6,073,124. The critical claim construction issue was definition of the term "download component". Both plaintiff and defendant got it wrong, but the CAFC (04-1445) said that the District Court got it right. As in Phillips v. AWH, intrinsic evidence trumped extrinsic.

Top Secret

5,286,129, owned by Crater Corp., claimed a conduit coupler for various uses, including electrical conduits and fluid flow systems. Lucent Technologies approached Crater to share trade secret information about the Crater coupler. The two companies coupled on the coupler, until the relationship came uncoupled.

Breaching the agreement with Crater, Lucent produced an infringing coupler, which it sold to the U.S. Navy. Protecting Lucent, the Navy had the whole business declared a state secret.

Court Legislation

Courts are forced to interpret a law only because a law requires interpretation. In effect, the judiciary necessarily acts as a legislature when the legislature abdicates. Case in point: 35 U.S.C. §271(a).
