Patent Standard

Historically, some standards committees have been naive, blind to adopting a standard incorporating patented technology, with the result that adoptees of the standard had to fork out patent license fees to a company having kept its mouth shut until the standard was set and widely adopted. This happened with standards for images (.gif & .jpeg), DRAM, and wireless communications. Now, at least one standards setter has set a standard in being patent savvy.

Amazon Bows

Amazon's 2006 Q3 earnings report, filed with the SEC last Thursday, revealed that Amazon settled with Cendant in its infringement assertion of 6,782,370, an ecommerce recommendation patent. A year ago, Amazon settled a similar suit from Soverain Software for $40 million, another settlement revealed through SEC filing. Is this an omen for the IBM assertion against Amazon? Does the pope wear a robe?!

Pissed Away

Aussie Dr. Alexander O'Neil invented a urinary catheter (4,652,259) that reduced the risk of urinary tract infection by limiting the length of the catheter sheath to stop short of a natural pressure barrier in the bladder. Dr. O'Neil also stopped short of disclosing the known best mode in his 1979 patent application, finally rectifying the specification in his 1985 CIP. But O'Neil had published an article with specifics in 1982. [CAFC 05-1241]

Big Blue Whacks Amazon

Patent powerhouse IBM has filed suit against Amazon in the Eastern District of Texas. IBM first notified Amazon in September 2002 of its "licensing opportunity", but Amazon balked. As IBM isn't exactly known as Mr. Sloppy, Amazon is either out to lunch, has hidden cards to play, or a bit of both.

20/20 Take 2

While others rattle on with their own bias, Professor Gregory Mandel of Albany Law School attacks hindsight bias with empirical research and well-reasoned analysis. "Humans are cognitively unable to prevent knowledge gained through hindsight (here, that the invention was achieved) from impacting their analysis of past events, as required for the proper ex ante analysis. Because of this hindsight bias, individuals routinely overestimate the ex ante predictability of events after they have occurred." Mandel's paper is crucial reading for anyone not blinded by their own bias to hindsight.

Hush Hush Patenting

Under the Invention Secrecy Act of 1951, the government may impose a secrecy order on patent applications whenever the disclosure "might be detrimental to the national security." Secrecy can be imposed even when the application is filed by an individual or company without government sponsorship or support. In such instances, the patent grant can be withheld.

Reissue Reissue Issue

Medrad was granted 5,494,036, "Patient infusion system for use with MRI." But the patent itself needed an infusion, so, within two years of issue, Medrad filed for a reissue. It got the reissue (RE 37,602), but in the process, neglected to file a reissue declaration (per 37 C.F.R. § 1.175). Asserted, it fell on the procedural error. So, Medrad filed for a reissue of the reissue (RE 36,648). But that didn't fly in court either, because the basis of the 2nd reissue was procedural, deemed outside the scope of the reissue statute (35 U.S.C. § 251). In the appeal (CAFC 06-1082), § 251 is interpreted as offering broad relief as a curative for prosecution error.

At the turn of the century, Silicon Valley debutante Transmeta shipped a low-power microprocessor, the Crusoe, a promising debut for the laptop and portable device market.

Now Transmeta claims Intel tucked into its Pentium Transmeta's patented technologies.

Claim Construction Incongruity

Broadcom and Qualcomm have been entangled in litigation for years, filing suits and countersuits in venues all over the country. Broadcom tried to get the ITC on its side, but the issues are so complex, the assigned administrative judge backed off, postponing a decision. Down in San Diego, Qualcomm home court, Judge Anthony Battaglia asked the chairmen of the two companies, Broadcom's Henry Samueli and Qualcomm's Irwin Jacobs, to hunker down and reach an agreement for 10 pending lawsuits. To naught.

Dyeing the Prior Art

Every obviousness case it gets nowadays, the CAFC polishes its chops by elaborating its flexible interpretation of anticipation via prior art combination, preening to the Supreme Court for the upcoming KSR v. Teleflex battle. In Dystar v. Bann (and Patrick), a patented dyeing process was found valid and infringed by the district court judge, who scalded the defendants a whopping $90,000 in damages (that's right, $90,000). Reeling, they appealed (CAFC 06-1088).

This story courtesy of Google News, whose fancy algorithms aren't smart enough to distinguish news stories about patents from those on patent leather.
