The embattled owner of Frank Lloyd Wright’s landmark Price Tower in Bartlesville Oklahoma has filed suit against The Frank Lloyd Wright Building Conservancy in order to void liens which have been placed on the property, the New York Times is reporting. The nonprofit had previously taken action against the Copper Tree Group, which is managed by investor Cynthia Blanchard, in order to prevent sales of original furniture from the building that were under the protection of a preservation easement dating to 2011.

Blanchard's attorneys are repeating their original claims that the orders no longer pertain post-sale. The company is now seeking $75,000 in damages in addition to an injunction against the Conservancy for "interfering" with the sale of the building or furniture. In yet another complication, the Times reports its previously scheduled October 7th auction has been pushed back to November 18th in response to a separate lawsuit from a Tulsa-based developer who claims to have signed a contract with Blanchard this May to purchase the tower for $1.4 million.
