Lacavera v. Dudas, on 37 CFR 10.6(a)

In Lacavera v. Dudas, the CAFC reviewed the propriety of restrictions placed on a non-citizen patent attorney. Lacavera was a Canadian citizen and a nonimmigrant alien. Perhaps in the future we will see issues pertaining to patent drafting and prosecution by folks in India.

The CAFC cited Chevron v. Natural Res. Def. Coun., 467 US 837, because the PTO is charged with administering the patent statute.
