This chapter will delve into the relationship between intellectual property (IP) and human-computer interaction (HCI), examining how intellectual property rights and limitations influence the design process, drive technological progress, and shape user experiences.The chapter provides detailed discussions of the three main types of IP providing recognition and/or financial benefit for what people invent or create: patent, copyright, and trademark.

When Ezra Pound launched his writing career in London in 1908, English copyright was governed by an Act of 1844, which required registration of works at Stationers’ Hall in order for copyright to be secured. The Act was soon replaced, however, by the Imperial Copyright Act of 1911, under which copyright protection was extended to works upon creation without the need for registration. Notable among the changes effected by the Act of 1911 was the extension of the term of copyright to life plus fifty years (subject to certain exceptions). Previously, the law fixed the term of copyright at either forty-two years from first publication or the life of the author plus seven years, whichever proved the longer. Two provisions allowed for compulsory licenses as a limitation on copyright.
