The former British design law permitted registration of the design of part of an article, but only where the part was "made and sold separately". We note (with thanks to Pakpat World Intellectual Property Protection Services) that, following the Pakistan Registered Designs Ordinance 2000, it is possible to register the design of part of an article in Pakistan provided that the article can be made and sold separately.

Although the UK law has changed as regards applications filed since 2001, it remains in force for those designs applied for before that date. Many other countries have the same provision. A Hong Kong case, Bang & Olufsen v To Hok Chung, illustrates how the provision operates in practice.

These cases concern designs of separate parts of articles, rather than designs of integral portions of an article (or, viewed differently, portions of the design of an article). In such cases, the former UK practice allowed the applicant to highlight the portion concerned by the use of dashed lines or a red ring, and then indicate that it was the novel portion in the "Statement of Novelty". However, protection was still obtained only for the article as a whole, and whilst the result of the Statement of Novelty was to increase the importance of the highlighted features, it did not entirely eliminate others. In that respect, the new European system and UK system (which clearly states that protection is available both for the design of a separate component part and for the design of part of a product, in other words an integral part) represents a significant advance in protection for applicants.
