This is more of a trademark issue than copyright, unless the image of your character is identical to the Marvel character.

I am not sure what database you are talking about as I do not use Justia to search for patents.

This is going to require that a patent attorney take a deep dive on the material that you provided and the nuances of the issued patent claims. There may be a path to correct inventorship to add you as one of the inventors. If you did not assign over your rights, then being a coinventor makes you... Read more »

This depends, as usual, upon a review of the detailed facts regarding the alleged "trade secret" in your case.

In order to obtain a patent, you will need to show that your pickleball is not just different from the existing pickleballs but differs in a way that would be non-obvious to a non-creative expert in pickleball design.

In order to sell pickleballs, you need to be clear of all relevant... Read more »

Yes, I highly recommend you to contact your local patent or IP law attorney to review it for potential infringement.

I depends on whether the "idea" you wish to use "from the patent" is captured and within the scope of the patent's claims. The claims are numbered sentences at the end of the patent, of course, and you may be able to get some idea on your own, but it may be necessary to... Read more »
