Some patent cases where a patent troll lost the lawsuit

Question

I am searching for few patent cases where a patent troll lost the case. My list includes cases which ended in one of the following ways -

1. Defendant wasn't infringing the patent(s)
2. Patent of patent troll got invalidated
3. Patent troll dropped the case due to whatever reason.

Here's an example case -

A troll, WiLAN, filed a patent case against Apple in 2011. Apple won the case by successfully proving that Apple's product do not infringe the said patent.

Another patent holding company, Bascom Research LLC, sued Facebook and LinkedIn over an obvious concept of "Documenting objects". Facebook & LinkedIn successfully argued about the validity of Bascom's patents. The case ended in favour of these tech giants and Bascom's patents were invalidated.

I will be really grateful if you can help me find these type of cases. My purpose is to find few key points about how a company won against a patent troll.

Please don't bother too much, you can just tell me the involved party names or even just a link to the article published about the case.

Thanks,

Take the names there, google them, find the cases. The list of companies is huge, you should find hundreds of lost cases. If you have access to a database that lets you search for court cases with a company name it should be easier.

How about this one?

And: "Uniloc, perhaps best known as Patent Troll in Chief, suffered a pretty devastating blow ... The Patent Trademark and Appeals Board has ruled that Uniloc's patent number 5,490,216 is invalid via an inter partes review (IPR). Essentially an IPR is a way for inventors to challenge a patent without getting federal courts involved. ..." Patent Troll Defeated

Here is a scientific article that developed an algorithm for defeating patent trolls in the 3D printing space, perhaps you can get some ideas here:--- A novel approach to obviousness: An algorithm for identifying prior art concerning 3-D printing materials
