If you do settle without getting a summons and complaint filed against you in a federal court, you don't think other copyright trolls won't notice and send other demand letters your way?
You raise an interesting factor that I have not previously considered in the calculation; that is, the longterm impact or “what impact will this have on future copyright claims?”
However, I would weigh the factor differently. If someone resolves the claim prior to a lawsuit, which is a public document, being filed with the court, there is very little chance that any other copyright troll would find out about the claim. Conversely, if the lawsuit is filed, the lawsuit is available for anyone to see online, this seems much more likely to draw more copyright demand letters. If I represented plaintiffs, I might be inclined to build a list of people/businesses who were sued for copyright infringement and have my clients search those websites.
Also, in general, a person/business becomes a more attractive target for copyright lawsuits after they have been sued once. It makes it much more difficult for a defendant to claim that they were unaware of copyright law or the duty to make sure pictures are properly licensed after that person has been sued for copyright infringement. Plus, a judge is more likely to punish a defendant that the judge believes is a repeat offender.
I think this factor weighs in favor of resolving the claim in the pre-litigation stage. The weight of the factor would probably increase if the alleged infringer has a lot of web content and uncertainty about the licensing history of some of the images on the website. This should be a non-factor if the person/business is absolutely sure there are no other infringements on their website.
I am curious as to how you think other copyright trolls would become aware of a claim that is resolved in the pre-litigation stage, especially considering how these claims probably all involvem confidentiality as part of the settlement. I suppose theoretically that the lawyers could be sharing information with each other, but this seems very unlikely as it would pose several serious risks and could seriously harm their clients by violating their settlement agreements. Am I missing something?
