It is one. I've heard oral history from Larry Nichols of Devon Energy talking about how examples like that were used by Devon to avoid disaster in acquisitions they'd made in Canada. He's on the Tulsa University Oral History "Voices of Oklahoma" website. I was in a a startup acquired by a Canadian company and we had the converse problem - the technology was rejected like an organ transplant by the engineering staff. Bizarre, because the whole idea was to generate revenue to support their other development efforts. Didn't matter - not invented here.
