I mean by public a person, a civilan acting on his or her private time, a user of the web. I am really not aware if I can enter the building being an homeless in San Jose, Ca, USA. I follow the Law at all time; but I am not a member of any group or any companies.

  • It would help if you could take another pass on this question. I'm not completely sure what you are asking when you say "buy a patent" (I assume you mean "file a patent") although @DonQuiKong's answer is good, high-level advice. Be aware, the grant of the patent is what you'd ultimately need. If it's a design patent, this will be simple, inexpensive and quick. If it's a utility patent, it will take a few years to find out whether you receive a grant, unless you pay for expedited review. You also want to explore international filing, although that can get very expensive.

1 Answer 1


A few hundred dollars at first, around 5-8 thousand if you want a patent attorney.

Later the maintenance fees go up, but you can always abandon the patent / application.

  • Adding to DonQuiKong, you probably want to look for a solo practitioner as opposed to a firm, for budgetary reasons (less overhead = lower rates.) In my experience, there are many such attorneys, and they will consult with you at no charge. Also, flat rates are often offered and probably a good idea.
