Earlier this week, a thick-waisted but thin-skinned Nathan Myhrvold, Intellectual Ventures CEO, ventured into incoherence, jockeying defensively when questioned by grizzled technology reviewer for the Wall Street Journal, Walt Mossberg: "Don't call me a patent troll," and "I'm not abusing the patent system."

Landmark Screens had Thomas D. Kohler file a patent application in 2002 for an electronic billboard. Allegedly, after a restriction requirement, Kohler dropped claims and supposedly filed a divisional. But, according to Landmark, Kohler screwed up, lost continuity, thus losing the original priority date, making the parent and its own billboard prior art. It seems that the so-called divisional omitted the specification - nothing but a sheet of paper indicating that a divisional was being filed. Landmark sued for malpractice last week.

The common approbation "junk patent" is typically stuck on "patent trolls," that is, inventors asserting their rights. Only rubes buy that. Companies regularly pitch junk at each other. Case in point: Dow Chemical, whose advertising tripe is "responsibility begins here," found guilty of malicious patent assertion.

TubeMaster makes custom catalyst reactors. Cat Tech asserted 6,905,660. Tubemaster counterclaimed for declaratory judgment (DJ). The district court granted summary judgment of non-infringement based upon claim construction, including DJ on non-accused configurations. Cat Tech appealed. A CAFC panel crafted crucial case law on declaratory judgment.

Bow to Light

Gertrude Neumark Rothschild developed a process necessary for making blue, green, violet and ultraviolet (high spectral) LEDs, used in many products, including flat-screen TVs, cell phone screens, computers, and traffic lights. All told, a market estimated at $7.2 billion. 4,904,618 and 5,252,499 were Rothschild's reward. Several semiconductor makers have licensed the technology, including Sony. From an ITC complaint filed in February, over 30 companies are still under the gun, including Hitachi, LG, Nokia, Sharp, Samsung, Toshiba. More settlements are in the offing.

Another Piece

Most junk patents are created by incompetent prosecutors, with an assist from incompetent examiners granting bad claims. Example in point - Arthur A. Collins got a couple of junk patents: 4,701,907 and continuation 4,797,589. '907 sunk by §112 ¶2, an unconstruable claim term. '589 down on non-infringement over missing a limitation, and claims "invalid for improper reexamination amendment." Appeal offered no real reprieve.

Such As

CAFC caprice is further confirmed in today's non-precedential Lawler v. Bradley. Bradley settled a patent infringement suit by Lawler by taking a license which was too complicated and unclear in its terms. 10% royalty on the actual selling price of infringed values. 10% on "average" selling price of products combined with the infringed valves. Lawler tried to terminate the agreement on a pretext that the district court blew off, but that a 2-1 CAFC majority, eschewing dictionaries and common sense, read differently.

Enhanced Execution

After seven years of preliminaries, trial began last week. Cornell University, one of the eight Ivy League colleges, is suing Hewlett-Packard in Northern New York for infringing 4,807,115, claiming enhanced CPU execution. A judge experienced with patent cases flew in from Washington, D.C. Cornell says that HP reaped $36 billion in the 1990s selling infringing supercomputers. Cornell wants damages through the life of the patent, though "laches bars a patent holder's claim for damages accrued prior to suit." A.C. Aukerman v. R.L. Chaides Construction, 22 USPQ2d 1321 (Fed. Cir. 1992). Laches may also apply in Cornell's failure to timely bring suit.

Hal Wegner has his knickers in a twist:

Beyond the anonymous attack launched against the PTO by an "Institute for Progress", Professor Dennis Crouch in his highly reliable blog, Patently O, has now exposed a patent attorney or agent who has launched an anonymous website, "USPTOExaminers.com", as a way for practitioners to anonymously post criticisms of individual Examiners. Both examples of anonymous criticism are unacceptable, but the latter is far worse as it posts attacks against individual Examiners who have no way to defend themselves.

There appears to be a rampant addiction to poor claims drafting, injecting claims with vague language, unnecessary legalese, and unbounded scope. This addiction spirals downward into a vat of confusion during prosecution, and eventually hits rock bottom during litigation as judges try desperately to resuscitate claim meaning. Examiners refuse to help, acting as enablers to this dangerous obsession.

John Wong got 5,568,779 for TALtech, claiming a seam for wash-and-wear dress shirts that don't pucker when laundered. Wong didn't disclose all the prior art he knew of, including the prior art that was the inspiration for his invention. The district court found inequitable conduct. The appeals court starches that shirt: "If the material is cumulative to other disclosed material, as a matter of law, the inventor is not obligated to disclose it." And, a lesson on best mode.

In an ongoing tussle in various venues, Microsoft had accused patent bad-boy Alcatel-Lucent before the ITC of infringing four patents claiming telephone/computer integration.

Conflict and Cooperation

Culture and law intersect at the personal level. Everybody lives in the two worlds simultaneously. But lawyers often behave as if there is no world but law.

This was not a mistake made by the Founding Fathers of this nation. To be fair to us today, except for one day in September of 2001, we have not had much visceral experience with how conflicts between culture and law may result in violence. But the Founding Fathers lived much of their lives in such conflict. And their fathers had lived much of their lives in conflict (that between church and state).

DuPont sued MacDermid Printing for infringing 6,773,859, claiming digital thermal printing. '859 was based on a provisional application. The USPTO mistakenly issued the patent without reference to the provisional. DuPont had that corrected. MacDermid brewed a tempest in a teapot over priority date, confusing the district court judge, who refused a motion to issue a preliminary injunction. On appeal, the CAFC (2007-1568) ruled that DuPont had met the requirements for 35 U.S.C. § 119, and set the priority date to the provisional filing. Vacated the motion denial. Remanded.

In The Weeds

Rep. Howard Berman, Chairman of the House subcommittee overseeing the USPTO, does his job in an April 29 letter to PTO Director Jon Dudas, demanding answers: did you sully the agency's reputation by consorting with RIM when it was under the gun from NTP, and you had NTP patents under reexamination?; why haven't you considered deferred examination?; explain inconsistencies in patent application projection for the future; document methodology in meeting application demand; why so pig-headedly clueless about examiner attrition?; justify managerial lurching in its various incarnations. One surmises from such inquiries that, under Dudas' direction, the PTO hasn't exactly been on the path of probity.

'007 was more Cylon, seeking "to capture a system that processed financial accounts 'without human intervention.'" The '007 claims mutated as well during prosecution.

Stranded R&D

In 1980, Congress passed the Bayh-Dole Act. Overnight with its passage, universities and government-funded R&D labs gained a comparative advantage in funding R&D. Universities and government labs have a cost advantage in that many had already spent tens of billions of dollars setting up research labs for non-commercial purposes, including teaching and curious exploration. Many scientists and engineers found the prestige of academia, and the increase in professional freedom it promises, a compelling offer. The result has been a gradual shutting down of corporate R&D labs, and an expansion of industry collaboration with scientists and engineers now employed by universities and government labs.
