It’s a Plane: Significant Modifications do not Result in Substantial Transformation
Client Alert | 1 min read | 03.13.17
On March 10, 2017, U.S. Customs and Border Protection published a final determination under the Trade Agreements Act that the country of origin of a Brazilian-manufactured military cargo airplane would remain Brazil, even after the aircraft undergoes significant conversion into a civil fire-fighting aircraft within the United States. According to CBP, the U.S.-origin changes to the aircraft—which include removing and adding various systems and components to install fire suppression capability—are not sufficient to change the aircraft’s “fundamental identity” and thus, do not constitute “substantial transformation.” The CBP emphasized that the aircraft would maintain its “most important” systems, the “basic structural integrity and the aerodynamics of the aircraft” would remain unchanged, and there was no evidence to demonstrate meaningful changes to the aircraft’s power, speed and range, or to the electronics and instruments used to fly the plane.

Claim construction is a key stage of most patent litigations, where the court must decide the meaning of any disputed terms in the patent claims. Generally, claim terms are given their plain and ordinary meaning except under two circumstances: (1) when the patentee acts as its own lexicographer and sets out a definition for the term; and (2) when the patentee disavows the full scope of the term either in the specification or during prosecution. Thorner v. Sony Comput. Ent. Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012). The Federal Circuit’s recent decision in Aortic Innovations LLC v. Edwards Lifesciences Corp. highlights that patentees can act as their own lexicographers through consistent, interchangeable usage of terms across the specification, effectively defining terms by implication.
