Controlled transfer of interests.
(2) Controlled transfer of interests. A controlled transfer of interests occurs when a participant in a CSA transfers all or part of its interests in cost shared intangibles under the CSA in a controlled transaction, and the transferee assumes the associated obligations under the CSA. For example, a change in the territorial based divisional interests or field of use based divisional interests, as described in paragraph (b)(4), is a controlled transfer of interests. After the controlled transfer of interests occurs, the CSA will still exist if at least two controlled participants still have interests in the cost shared intangibles. In such a case, the transferee will be treated as succeeding to the transferor's prior history under the CSA as pertains to the transferred interests, including the transferor's cost contributions, benefits derived, and PCT Payments attributable to such rights or obligations. A transfer that would otherwise constitute a controlled transfer of interests for purposes of this paragraph (f)(2) shall not constitute a controlled transfer of interests if it also constitutes a capability variation for purposes of paragraph (f)(3) of this section.
