I don't know which patents you are referring to, but my cursory search shows that there are about 5 patents that list Victor Staats as the inventor. 4 of these have expired due to their age, and 1 expired because a maintenance fee was not paid. There are no enforceable patents for Victor Staats...Read more »
If you are making something that has been around 20+ years, then you very likely will not infringe any patents. After all, that is the idea behind patents: after a patent expires (currently 20 years from the filing date of the patent application), then anyone can use whatever is disclosed in the...Read more »
I processed a provisional patent in 2003 and did not follow up with a non-provisional patent due to cost. I made several operational prototypes from 2000-2007 of this device. I did discuss concept with an associate of a company. I just recently found out that In 2008, this company was granted a... Read more »
No. A provisional patent application that is not followed up with a non-provisional patent application is not published and does not result in a patent, and thus cannot serve as prior art against another patent case.
This is, unfortunately, a common problem. In your case, you cannot get a...Read more »
It sounds like you're asking for an intellectual property search for your grandfather. If you'd like to search this for yourself, you should search for his assignments in the databases at the USPTO (https://portal.uspto.gov/pair/PublicPair) and the Library of Congress...Read more »
That depends. Patent rights are country-specific, and therefore your question involves whether that company has a Chinese patent as well as a US patent. (Patent rights generally protect making using or selling the patented technology.) If the Chinese entity has any patent protection domestically or...Read more »
These appear to be a set of three US design patents and one US utility patent. A United States patent is effective against people that make, use, sell, or offer to sell an infringing product in the US.
So a US patent can be used against a product made in China and imported into the US, or...Read more »
for Example . Plant grow tent. If I took the basics of the tent , such as the building part of it and how it’s put together . However I changed the material used and actually used it for something totally different would I be able to patent that or stop other companies from selling the same thing ?
Your short question includes many key questions of patent law.
1) You do not infringe a patent. You infringe one or more specific independent claims (ones that start with no reference to another claim) and possibly some dependent claims (a claim that adds additional limitations to at least...Read more »
If there is a product currently in the market place which has always been manufactured using either leather or traditional wood from trees and I start manufacturing this product but instead of using leather or lumber from trees, I use a different material, like bamboo, which gives the item a very...

Using your example with respect to a golf bag. If the sole difference was that you used off-the shelf sheets of flexible bamboo leather substitute and made a bag from that -- then you would have a hard time getting a utility patent. Substituting one product for another where the modifications to...Read more »
I see that you filed a patent application and the PTO processed the application with an Office Action rejecting the claim as too vague to even examine. After a period of six months, the application was deemed abandoned. There is an indication in the file that the final notice was returned as...Read more »
This happens all the time. If it is not granted, and there is no likelihood of it being granted, then whatever is disclosed in the patent application is dedicated to the public. Anyone can use whatever is in the published application with or without modifications.
If the rights to the patent have been assigned into your company and you sell that company to buyer, then buyer owns the assets including your patent. You would not have the right to practice that patented invention without getting a...Read more »
I do not see why not. A patent is a piece of property and moves with much of the same rules. The USPTO system for recording ownership has a selection for letters testamentary which is a document issued by a probate court to an executor. See https://epas.uspto.gov/
If you have two inventions, then you will need to have two patents. If you have one invention, but it has several different flavors of the invention, then you can just file one patent application. Due to the costs, it is obviously beneficial to have everything in one patent application....Read more »
