This intensive, practical course will comprise a mixture of lectures, tutorials and hands-on practice with each of the free-of charge, public services available for the major national patent offices. Each participant will be given use of an on-line PC to give them maximum hands-on experience of how to use the patent legal status records and registers effectively. Private, encrypted services will be noted but not accessed. The course will be held on 10-11 April 2008, in London, United Kingdom.
