San Diego-based Trinity Orthopedics Inc. has acquired the patent portfolio of Portland, Ore.-based Expanding Concepts LLC for an undisclosed sum, Trinity said.

The patents will help Trinity Orthopedics expand its products that aim to reduce the complications associated with spinal surgery, the company said, in a statement.

Trinity Orthopedics was launched in 2004 by physician James Marino, the founder of San Diego medical device maker Nuvasive Inc. (Nasdaq: NUVA).
