The standard answer is to engage an attorney to do a freedom to operate search and give you a written opinion. This presupposes that you know what you are building and how it works in some detail. The search would look for patents that are in force that have claims that look like they might cover what you are building. Since you are in the early stages of ...

The requierements for a patent are novelty inventive step (called non obviousness in the US) usability. Novelty is anchored in 35 USC 102, which reads (a) NOVELTY; PRIOR ART.—A person shall be entitled to a patent unless— (1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available ...

Is there a way to contact the patent holder and ask him if he used it for commercial purposes, and if so, where/how? Search through the file history using USPTO PAIR to find out inventor information.

You can always try to negotiate the terms of your contract. However, I doubt anyone would hire you on the basis of a paying you for your time and also getting a fraction of the patent earnings. The standard consulting agreement essentially says "I hire you to do work and I own the work product". Normal design engineering and modeling of an idea brought to ...

Long and complicated claims ...

There is a provisional application for patent, which is not a patent of any kind; meaning it does not provide an enforceable property claim. A provisional patent application (PPA) simply reserves the right to file a non-provisional application within a year,...

I am not well versed on design patents, so I'd like to hold off on answering that part of you question. However, from what I can deduce, a provisional application is not likely an option. Provisionals are a precursor to a utility patent. Utility patents do not apply to designs of decorative elements.

Product design, mechanical engineering, and 3D modeling is work for hire and not part of the inventive process unfortunately. Does it add value? Yes. Does it add more value than you charge for your services? Maybe. Makes a good selling point but it doesn't change things. It's still work for hire. Inventing is outside the scope of the work requested. But if ...

The Wayback Machine is actually the closest thing available for this too, even if it's not quite the main purpose. This should show, in most cases, at least when a product is offered for sale. Though its dating is relatively coarse, and it certainly wouldn't do anything to show non-Internet offers, nor actual sales. Archive.org is actually prior art too, ...
