At the moment, only the police have the power to enforce offences under the CDPA. Trading Standards will, as from 6 April 2007, also have powers to enforce copyright offences, including the power to make test purchases and to enter premises to inspect and seize goods or documents. Obstructing them will be an offence.
Expect to see squads of suitably armed TS officers swarming around car boot sales and markets in search of bootleg videos as from next month.
Guidance on the new powers is available from the Patent Office here.
