Beware of Oververification of Lawful Permanent Residents
Client Alert | 1 min read | 04.25.14
On April 24, 2014, the Department of Justice announced the settlement of a discrimination claim against the supermarket chain Mexico Foods LLC, aka El Rancho Corp., alleging, in part, that El Rancho's practice of requiring employees who are lawful permanent residents to present new employment eligibility documents once their permanent resident cards had expired violated anti-discrimination provisions of the Immigration and Nationality Act. The settlement serves as a reminder that, although an employee's permanent resident card may expire, the lawful permanent resident status does not, rendering re-verification of cards unnecessary -- even for ensuring the person remains a "U.S. person" for purposes of U.S. export control laws-- and exposing employers who engage in the practice to potential liability for discrimination.

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.
