Actually, I did a trademark search
While a trademark search is a good idea, and staying clear of marks that such a search turns up is also a good idea, it's not so clear-cut a problem:
- You don't need to register a trademark to use it as a trademark and to gain some protections thereof (the difference between 'TM' and 'R'). It's a good idea, in the same way that if you think it's going to be contentious registering a copyright is a good idea, but if you're using a trademarkable name for a product and someone else comes along and sells his product under the same name, then you can sue him for trademark infringement regardless of whether you bothered to register. It's just that the court case will be a lot more clear-cut if you did.
- If a trademark owner doesn't use a mark, or doesn't actively protect it, then they lose it. Since trademarks are market-specific, it means that if (for example) Lockheed Martin had registered F-22 for the confectionery market, with the intention of making Raptor-shaped cookies, then failed to actually do so (for, IIRC, five years), then you would be at liberty to sell your confectionery under the name 'F-22'.
- I could be wrong, but as I understand it there's no oversight on trademark registration, and registration doesn't automatically grant you mark rights you wouldn't otherwise have - at least in the UK and US - so I can register a trademark which is actually used and owned by someone else, and unless it's obvious it will only get noticed if they search for it themselves or try to register the same mark (or some legal squabble comes up and catches their attention) and if they've demosntrably been in that business longer than I have, then I could lose my registration.
So it could also be that you search and find a registration for a mark which is actually invalid or has lapsed and nobody's noticed yet, and it could also be that you search and find nothing, but that trademark does actually exist in the market you're intending to use it in, it's just not registered or catalogued.
