Although I manage patent portfolios internationally, I presume my services will be for U.S. only. I am an expert on the entire patent procurement process, including patentability work, writing the patent application, and corresponding with USPTO.
I also have experience writing design patent applications, and the interplay between design patents, trade dress, trademark, and copyright law.
*Note* - You wouldn't hire an unlicensed foreigner to defend you in a criminal trial in the U.S., so why hire one to protect your IP (and waste your money)?
