Earlier this month Apple was granted another Thunderbolt related patent. Wikipedia notes that Thunderbolt (code named light Peak) was co-developed by Apple and Intel and made public in 2011. Apple applied for the Thunderbolt trademark shortly thereafter and came close to getting it registered. In fact in 2012 they were 30 days away from approval before running into problems and since then Apple has been trying repeatedly to get it registered with no success. In fact the US Patent and Trademark granted Apple their fourth approval extension on April 29, 2014. As Apple continues their trademark efforts in the US, a new positive development is occurring with Thunderbolt in Canada.
