Markman v. Westview Instruments, Inc., 517 U.S. 370, 116 S.Ct. 1384, 134 L.Ed.2d 577, 64 USLW 4263, 38 U.S.P.Q.2d 1461, 96 Cal. Daily Op. Serv. 2788, 96 Daily Journal D.A.R. 4642

Facts

Petitioner Markman owns a patent for an inventory control system used in dry cleaning, which tracks clothing through the cleaning process. Markman's system utilizes a keyboard and data processor to generate transaction records, including bar codes. Westview Instruments, Inc. developed a similar product that also uses a keyboard and processor but claims it only tracks invoices and transaction totals, not the actual clothing inventory. After a jury found Westview's product infringed Markman's patent, the District Court directed a verdict for Westview, leading to an appeal.

Petitioner in this infringement suit, Markman, owns United States Reissue Patent No. 33,054 for his 'Inventory Control and Reporting System for Drycleaning Stores.' The patent describes a system that can monitor and report the status, location, and movement of clothing in a dry-cleaning establishment.

Issue

Whether the interpretation of a patent claim is a matter of law reserved for the court or subject to a jury's determination under the Seventh Amendment.

Whether the interpretation of a patent claim is a matter of law reserved for the court or subject to a jury's determination under the Seventh Amendment.

Rule

The construction of a patent, including terms of art within its claim, is exclusively within the province of the court, as established by precedent and the need for uniformity in patent interpretation.

The construction of a patent, including terms of art within its claim, is exclusively within the province of the court.

Analysis

The Supreme Court analyzed historical practices regarding patent claim construction and determined that, historically, judges, not juries, were responsible for interpreting patent specifications. The Court emphasized that the Seventh Amendment does not guarantee a jury trial for the construction of patent claims, as this task is more suited to judges who possess the necessary expertise to interpret complex technical language.

The Court has repeatedly said that the answer to the second question 'must depend on whether the jury must shoulder this responsibility as necessary to preserve the “substance of the common-law right of trial by jury.”'

Conclusion

The Supreme Court affirmed the lower court's ruling, concluding that the construction of a patent claim is a legal question for the court, not a factual question for the jury.

We now affirm.

Who won?

Westview Instruments, Inc. prevailed in the case because the Supreme Court upheld the lower court's decision that the interpretation of the patent's claim terms was a matter for the court, not the jury.

Westview responded that Markman's patent is not infringed by its system because the latter functions merely to record an inventory of receivables by tracking invoices and transaction totals, rather than to record and track an inventory of articles of clothing.
