ChipIn.com Trademark Dead - Still a concern?

[RegFee]

ChipIn.com will be going to auction soon (~2 hours!) on NameJet

ChipIn used to be a crowdfunding site, but it looks like on Feb. 4th 2013 a company called InMobi acquired it and subsequently shut it down. A cached version of ChipIn.com shows the following notice:

Thanks For All The ChipIns

February 4, 2013

This is to notify all users of Chipin.com website ("Website") that ChipIn Inc. has been merged with InMobi Technologies Pvt. Ltd (collectively referred to as "Company"). We further wish to notify that InMobi has decided to discontinue the Website and all services thereunder on March 7, 2013 ("End Date"). Effective from the End Date, all registrations of any organizer/customer/user will be automatically cancelled/terminated without further liability to Company. Any personal data related to you, which may have been collected through the Website shall be destroyed as per the terms of the Privacy Policy provided under the Website.

InMobi will continue to own and hold on to the ChipIn brand, domain, and technology.

As of the date of this notice it will no longer be possible to create new accounts or ChipIns. Those with existing accounts will still be able to log in, copy and export data, manage ChipIns, update ChipIn pages, and accept contributions until the End Date. Chipin.com was started in 2005 as an easy way for individuals to raise money collectively and was one of the pioneers in this field. In six years Chipin.com helped thousands of users raise millions from contributors for wide-ranging purposes, including heart surgeries, pet adoptions, college graduation, disaster funds and much more.

Thank you for being part of the ChipIn community! It is gratifying to know that it has made a positive difference for many.

Assuming the inMobi mentioned above is the same company that currently runs inMobi.com, they are still very much alive. Even though they said they would continue to hold on to the brand and domain, according to the USPTO, their trademark expired that November.

According to a message from the co-founder found here, "after two years of giving the group donation concept a good try without getting much traction, we decided to take a 180-degree turn and evolve the company into something very different - a Flash widget maker "

So to finally get to my point, crowdfunding is now a very popular, and "Chip In" is about as brandable and applicable a name you can find. Assuming inMobi didn't let this expire on purpose, do you think they would have legal grounds for getting the name back, or is letting the trademark expire a company's clear message that they no longer care about their property?

I don't plan on bidding on the name, so I'm not trying to discourage people here.
