Richard Baker of West Newbury qualified as a candidate on the Republican ballot for the Sept. 16 primary.
He is running for congressman from the Massachusetts 6th Congressional District, the seat now held by Congressman John Tierney, D-Salem, and so far is the only challenger.
Baker, 49, submitted 2,266 certified signatures to Secretary of the Commonwealth William Galvin's office last Friday, more than the 2,000 required to qualify for the ballot.
Baker, an inventor and former Pentucket School Committee member, is the director of intellectual property licensing at 3Com Corp. in Marlborough.
A campaign kickoff will be held Thursday, June 12, at Sylvan Street Grill in Peabody. Tickets are available at www.richbaker08.com.
