I had a software developer create a software program, which I copyrighted and then assigned to a software company (and LLC) that I co-founded. I plan to sell the program to the general public.
Then I discovered that there's a competitor that has a program with a similar idea, although the functionality, look and feel, etc. of our programs are certainly different. The other program is copyrighted, I think, but doesn't seem to be patented.
I'm concerned that the competitor would try to drive me out of the market by threatening a lawsuit for copyright infringement (or suing and running up legal bills), even though my lawyer said that there should be no basis for that.
Any tips on how to avoid claims of software copyright infringement, or any other problems that could arise from this scenario? Thank you.
