The activities in the year 2000 of some 24 intellectual property offices and organisations world wide in the field of patent information are summarised. The summary is presented under nine standard headings, as far as relevant, for each country. Activity varies enormously from just a handful of applications through to CA (39K), DE (62K), and EP (143K), the numbers continuing to increase significantly in most countries. This is the first of two parts, covering 50 countries and organisations; this part deals with those having WIPO codes starting A–I, and Jamaica. 相似文献

The activities in the year 2001 of some 46 intellectual property offices and organizations worldwide in the field of patent, trademark and industrial design information are summarized, based on the Annual Technical Reports (ATRs) provided by those offices and organizations. The summary for each country commences with filing statistics, followed by the most relevant, new features of their information activities. Both the filing and information activities vary enormously.The author concludes, inter alia, that
- 1. In most industrialised countries as well as some of the emerging countries, the number of IP rights applications continued to increase.
- 2. The granting/registration procedures have not kept up in many IP Offices with this increased number of applications.
- 3. Work on systems permitting electronic filing of applications, correspondence and fee payment is continuing at a great pace.
- 4. CD-ROM, DVD and the Internet are now the major vectors for disseminating IP information.
- 5. The value of the ATRs, and their chronological and geographical comparisons, is increasingly limited by the absence of many ATRs each year and the repetition of information already provided in previous ATRs.
