On A Treadmill

Meanwhile, the company puts the invention into its product. Then, when faced with patent infringement, shrug and claim that the company invented it.

Being Clear

Terlep v. Brinkmann hinged on claim construction, specifically the definition of the word 'clear', in reference to an LED. The district court ruled that 'clear' meant more clear than less clear (as in, translucent). On appeal by Terlep, wishing things were a little less clear, the Court of Appeals (04-1337, August 16, 2005) reviewed the stack of claim construction evidence in the priority set forth in Phillips v AWH, and agreed with the district court. Ditto applying the doctrine of equivalence during infringement analysis, particularly in light of the precedent of Festo.

AnimalConcerns.org is squealing about a Monsanto patent application (WO 2005/015989) which claims "methods for producing improved swine genetics." AnimalConcerns oinked: "Monsanto Corporation is out to own the world's food supply, the dangers of genetic engineering and reduced biodiversity notwithstanding, as they pig-headedly set about hog-tying farmers with their monopoly plans. We've discovered chilling new evidence of this in recent patents that seek to establish ownership rights over pigs and their offspring."
