Question
QUESTION: Hello, I am wondering if Patent Assistance Worldwide is a reputable company. I researched them and they have some affiliates but I can't find much more about them. Plus, they are not on the list of company complaints that are on the patent government site. Thank you for your help.
ANSWER: No!
These weasels constantly come up with new names. My web site,
http://www.evansville.net/biz/patagent has a link to the Ron Riley Scam Alert site. The link is on my Inventors Resources page. You will find at that site, general info on how scams operate, and you will probably find at least some of the subsidiary companies on it.
Don't send them any money! Also, beware of any "inventors help or promotion" organization that has a general broad name, as opposed to an individual registered as an agent or attorney with the U.S. Patent Office as a patent practitioner. Especially beware of such firms advertising on this site, even on my profile page. I have pointed that out to Allexperts but they claim they have no control over who advertises with them, they blame Google.
Best wishes on your project.
