Invista Performance Technologies has acquired from La Seda de Barcelona intellectual property relating to its purified terephthalic acid (PTA), polyethylene terephthalate (PET) and related process technologies, including the full rights to exclusively license the technologies in the region comprising Europe, the Middle East and Africa.

In 2000, the ownership of intellectual property and licensing rights for this region transferred to a regional joint venture company established by Invista's and La Seda's predecessors. Until today, licensing has required collaboration between the two companies.
