In decisions in the cases C-146/13 and C-147/13 issued in May 2015, the European Court of Justice (ECJ) rejected two challenges by Spain against the legality of both unitary patent regulations.{{cite web|url=http://ipkitten.blogspot.co.uk/2015/05/breaking-news-cjeu-rejects-spains.html|title=BREAKING NEWS: CJEU rejects Spain's objections to the Unitary Patent Package|last=Smyth|first=Darren|date=5 May 2015|work=IPKat|accessdate=16 May 2015}} The decisions are significant because these legal challenges were regarded as "the last serious obstacle to the Unitary Patent Package being implemented", "provided the necessary number of ratifications of the Unified Patent Court Agreement occur (13 including UK, France and Germany)."

In case C-146/13, Spain challenged Regulation (EU) No 1257/2012 implementing enhanced cooperation in the area of the creation of unitary patent protection, and in case C-147/13, Regulation No 1260/2012 of 17 December 2012, implementing enhanced cooperation in the area of the creation of unitary patent protection with regard to the applicable translation arrangements, was challenged.
