If You Want a Broad Patent Construction, Be Careful What You Ask For

By Charles W. Shifley
June 27, 2008

In a recent case, a patent owner claimed to have invented side impact airbag sensing. The patent enabled an embodiment; that was stipulated. In opposition to a motion for summary judgment of invalidity for lack of enablement, the owner asserted that enablement of a preferred embodiment satisfied the enablement requirement of the patent law. It didn't. In Automotive Technologies Int'l., Inc. v. BMW of N.Am., 378 F. Supp. 2d 780 (E.D.Mich. 2005), aff'd, 501 F.3d 1274 (Fed.Cir. 2007), the District Court and the Federal Circuit held the patent invalid for failure to satisfy enablement. Did you know that enabling a preferred embodiment does not satisfy the enablement requirement? It doesn't. The ATI case is only one of several consistent cases. You should beware, and consider the matter in both patent prosecution and litigation. If you own a patent, and wish for a broad construction, be careful what you wish for.

The Patent Law's Enablement Requirement

The enablement requirement stems from 35 U.S.C. '112, '1:

The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same '

The enablement requirement 'insure[s] adequate and full disclosure so that upon the expiration of the [patent term] 'the knowledge of the invention enures to the people, who are thus enabled without restriction to practice it and profit by its use.”

Kewanee Oil Co. v. Bicron Corp., 416 U.S. 470, 480-81 (1974); see also AK Steel Corp. v. Sollac & Ugine, 344 F.3d 1234, 1244 (Fed. Cir. 2003).

The Stranger to the Deed Rule Image

In 1987, a unanimous Court of Appeals reaffirmed the vitality of the "stranger to the deed" rule, which holds that if a grantor executes a deed to a grantee purporting to create an easement in a third party, the easement is invalid. Daniello v. Wagner, decided by the Second Department on November 29th, makes it clear that not all grantors (or their lawyers) have received the Court of Appeals' message, suggesting that the rule needs re-examination.
