Add. Case: Arrythmia Research v. Corazonix (Fed. Cir., 1992)–A patented invention was
challenged in court. The invention converts the electronic impulses of a heart attack victim’s
electrocardiogram into digital information that can be analyzed by a computer program. Using
existing medical knowledge, the program alerts a physician when the patient has a high risk for
a second heart attack. The district court held that the formula for determining the risk of a
second heart attack was prior art and not patentable.
Decision: The federal circuit court of appeals reversed. “The number obtained by the program is
not a mathematical abstraction; it is a measure of microvolts of specified heart activity…. Claims
directed solely to an abstract mathematical formula or equation, including the mathematical
Add. Case: Ciba-Geigy v. Alza (D.NJ, 1994)–Ciba-Geigy acquired a patent for a nicotine
patch (Habitrol), that helps people quit smoking. Alza produced Nicoderm, a similar patch. Ciba
sued Alza for patent infringement. Alza claimed the patent was invalid.
Discussion: Alza’s motion for summary judgment is granted. The patent was anticipated by a
prior printed publication. More than a year before the patent application was filed, a letter from
Add. Disc.: The Supreme Court has held (Markham v. Westview), that the role of juries in patent
cases is limited. Judges are to determine the scope and meaning of patent terminology. The
construction of a patent, including terms of art within a patent claim, the key step in determining
most patent validity cases and infringement cases, is a matter of law for trial judges to decide.
Issues beyond that may go to a jury. The Court upheld the decision of the Federal Circuit (which
sits in Washington) that was created in 1982 and has exclusive jurisdiction over appeals from the
Patent and Trademark Office and patent infringement appeals from district courts. The result
has been more consistency in patent law than when all the appeals circuits were deciding patent
cases. The Supreme Court rarely questions decisions of the Federal Circuit on such cases.
TRADE SECRETS—Information protected by tort law that, 1) if known by a competitor
would, 2) cause the information owner to lose a competitive advantage, and 3) the owner must
take reasonable steps to protect the information. Most of the information protected by trade
secrets could be patented or copyrighted, but trade secrecy can last longer and the knowledge can
be kept from competitors. Hence, the success of the secret Coke formula for over 100 years.
Most businesses with trade secrets have employees that will know trade secrets sign statements
acknowledging that they promise not to reveal to others now or later when working for another
firm.
CASE: Bohnsack v. Varco (5th Cir. 2012)—Bohnsack invented a machine that helped in oil
drilling. Under a secrecy agreement, he discussed with Varco the possibility that it would
manufacture the machine. Talks fell apart and Varco then filed a patent application for the
machine. Bohnsack sued for trade secret violation and was awarded $600,000. Varco appealed.
Decision: Affirmed. Varco contends that it did not use the trade secret, but it exploited it in a way
likely to lead to enrichment, which constitutes use. Bohnsack tried to protect the secret by the
