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

But in the normal course of things, a patent application is published 18 months after that application (or a priority application) was filed. So for example US20170035603 A1 was a publication... Read more »

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 »

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 »

Not clear how they will get access to your business idea. If you mean will they be able to look at your provisional patent application, the answer is no (not unless you provide a copy).

A US patent covers a produce while it is in the US. So if you want to avoid the US patent, you need to avoid the US. That means the product cannot be in the US and you cannot make the sale from the US.

If you open an office in Canada to make sales and import products from China without... Read more »

A patent only applies to the country that issued the patent. (There are a few regional patent system but none that include the United States and Canada so we will ignore that nuance right now).

I am sorry but this sort of situation deserves a serious answer that will only come when a patent attorney looks at the accused product, the cease and desist letter, and the referenced patents. This is simply not a good candidate for casual comments on a public web site.

This does not seem to be a patent issue. When filing a patent application, one needs to submit the true list of inventors. From your description, I don't think that this person has patents that were issued with fake inventors.

I am not sure what type of scam is going on here but... Read more »

Your question did not contain the list. But even without seeing the list, I can warn you that some pending applications won't show up on a list. The default is that US applications are published 18 months after filing. So most applications filed within the last 18 months won't show... Read more »

2) There is a process to revive a patent for unintentional failure to pay a maintenance fee. There is a hefty fee for this. The petition is at... Read more »

The process wants the names of the true inventors. Inventors are not always the owners or the people that worked the hardest on making the prototypes.
