It seems unnecessary to provide links on how expensive attorneys are in the USA, and the costs of conducting any form of litigation.
However, the Court Docket states that Alarm Force and Eyetalk365 have reached a settlement, and are to bear their own legal costs. Go to https://search.rpxcorp.com/ and do a search. You'll find the docket.
Here are a few pointers to some of the facts I have relied on in calculating the likely level of settlement with Alarm Force:
Alarm Force is a Canadian Company on the Toronto Stock Exchange. Alarm Force filings are up to date, and it's annual report has been filed. The annual report sets out subscriber numbers, revenues and average subscription rates for Canada and the USA. Go take a look.

REVO lost it's claim for damages against it's previous patent attorneys. That claim was based on the attorney's failure to secure patent protection outside the USA. Follow this link for some details. http://www.ncbusinesslitigationreport.com/uploads/file/revolutionary.pdf give you the links.
