Implied licence

implied licence (intellectual property): a type of intellectual property right; a licence granted by one party (the licensor) to another (the licensee) allowing the exercise of certain rights over the licensor’s intellectual property, where the licence is not expressly set out in a written licence agreement but is deduced from the intent of the parties; an implied copyright licence, for example, will allow reasonable use of the copyright work by the licensee  where the licensor has implicitly consented to such use.
