Hi fellow hackers, I could use some help here. We developed an simple location sharing app 3~4 years ago, and got sued yesterday along with Apple, Google, Verizon, Sprint, T-mobile[1], Glympse[2] by some company called Remote Locator Systems LLC in Texas. They claim that we infringed their patent called "Method and Apparatus for Locating Personnel and Objects in Response to Telephone Inquiries". Any one know what we should do about it?

For everyone being sued, just search for the patent name "Method and Apparatus for Locating Personnel and Objects in Response to Telephone Inquiries" and look at the top 10 results from Google.
