Brodeur Partners and former client Blackberry have settled a $700K lawsuit by the PR firm, which claimed the former Research in Motion didn't pay for work on a "make or break" campaign for the mobile device maker.

Blackberry confirmed the "matter has been settled" but declined further comment. Brodeur declined to comment.

Both parties signed on to a dismissal of the suit in federal court in Massachusetts on Jan. 24, according to a court filing.

Brodeur claimed in the September 2013 suit that Blackberry induced the firm to work "around the clock" on the campaign for the troubled company from late 2012 into 2013. After an agency review amid that effort in the spring of 2013, Blackberry moved the account to APCO Worldwide and Text 100.

The suit claimed Brodeur spent more than 3,000 hours of billable time worth $700K outside of its regular scope of duties with the 16-year client.

Blackberry told O'Dwyer's in September that it pays "legitimate invoices" from vendors, adding that the charges were "without merit."
