Try calling a patent attorney in the state you live in. You might also try: 1-800-uspatent.

look it up on a search engine

Search your state website, then federal trademarks or trade names; check with local BBC and Chamber of Commerce; State Comptroller site, etc. Start search at local and state level, then search nationally. Use several  search engines as some will find different sites. Good luck.

I'm not sure if you will be able to find any patent information going back to 1748.  You might try your local county library and see what resources they have.

I don't recall the exact site, but if you google "patent" or "trademarks" it should come up or use ASK.COM w/the same search criteria

You can obtain a patent from the US patent office. It can take months to years, depending. You can use "patent pending" in the interim once you have actually applied.\n\nHere's where you start:\n\nhttp://www.uspto.gov/\n\nThat's the US patent office's website.\n\nHeop this helps, and good luck with your idea!\n--J.

I only know of some law website which help others to get their innovation patent. http://www.poormanpatents.com/\n\nIf it is something specific, then you could search on USPTO (http://www.uspto.gov) or http://www.inventionpatent.net/patent/about.cfm

Do a search at the Patent and Trademark office to see if the name has been trademarked. \n\nHowever, if they never registered the name, it will not be listed there. That being said, if they haven't registered their name, then chances are they won't have the lawyers to do anything about it.

If you have the patent nbr then look it up at the USPTO: \nhttp://patft.uspto.gov/netahtml/srchnum.htm\nEG: US Patent 5,146,634\n\nIf you dont know the patent nbr you can use the site to search for keywords and find it.\nhttp://patft.uspto.gov/netahtml/search-adv.htm\n\nIf it is a foreign patent there is a good chance you can find it using the EPO website.\nhttp://www.european-patent-office.org\n\nUnfortunately this can be a very expensive endeavor. There are firms who routinely charge $1500 - $3000 to get the true answers.  They have access to very expensive databases of patents and prior art.  IE: If your proposed invention has *ever* been detailed in a public document it is not patentable! Beware of the many sites who charge you only $295 for an 'inventor' search.  Most times these search results are extremely shallow and fall apart under close examination.  They just want your $300!  Do the search yourself at the free USPTO website. If it's a good idea you'll eventually need some serious money to get your invention safely and properly patented. I think the USPTO charges around $500 to process your application. They have 3-4 thousand examiners who will search for prior patents and prior art.  But they can be wrong too cuz there search is not exhaustive. They have a huge backlog of applications.

If you're trying to get a U.S. Patent...start by going to this web site -\nhttp://www.uspto.gov/\n\nIt's the United States Patent and Trademark Office.  They have all the info and forms you'll need.\n\nAlso, there are Patent Lawyers who will help you file your patent as well, but you will have to cough up some $$$ for that.

You can search and verify whether it is trademarked at the United States Patent and Trademark Office. Use their Trademark Electronic Search System(Tess) at http://tess2.uspto.gov/bin/gate.exe?f=tess&state=gakoho.1.1
