The public and private sectors have both invested heavily in recent years in the production of machine-searchable full texts of patent documents. Access to these databases enables even unskilled searchers to locate at least some relevant material for practically any search task. But full text provides only one viewpoint; there are circumstances in which neither the original text nor a machine translation provides sufficient keys to retrieve the best prior art. This article illustrates that comprehensive prior-art search results will only be obtained if the searcher understands the inherent quality (timeliness, accuracy, completeness) of the databases available, including any known weaknesses. © 2017.

The year 2014 is the centenary of the filing of a key US patent in the development of the modern zip fastener. The named inventor for this patent was Gideon Sundback, who had successfully improved the original designs of Whitcomb Judson. In addition to his breakthrough invention, Sundback was responsible for many additional patents during his long working life with the Hookless Fastener Company. Some of his inventions were patented outside of the US as well, but despite retaining foreign rights to himself, he did not make a great fortune from inventing. His last patent was granted posthumously, in 1959. © 2014 Elsevier Ltd.


Effective searching of electronic full texts of patent documents requires both appropriate search engine technology and high quality source documents. This article reviews the impact of both the historic development of online searching and of document preparation upon the resulting databases. Many standards were developed at a time when patent documents were wholly paper-based, and may no longer be suitable as current guidelines for the preparation of full text electronic databases. Part 1 previously discussed the impact of applicant guidelines and patent office practice upon the usefulness of title, abstract and claim for retrieval. Part 2 reviews the main part of a patent specification, to understand the challenges of using this for various types of patent retrieval. A short survey of the main providers of full text patent information concludes the review. © 2009 Elsevier Ltd. All rights reserved.

Part 2 concentrates on aspects of the main body of the specification, and whether new methods of document preparation and retrieval will improve patent search quality. © 2009 Elsevier Ltd.

Previous studies of the internet as prior art in patentability searching have concentrated on the difficulty of establishing a date of publication and a stable form of citation. The current work examines whether the internet is actually contributing new prior art, or merely replicating non-patent literature which can be obtained by other means. A sample of PCT international applications published in 2007 provides some evidence that certain ISAs are more effective in locating and citing internet-based non-patent literature than others. The sample also reinforces the widespread perception that non-patent literature forms a higher proportion of total citations in distinct technical fields. Some recommendations are made about bibliographic control of internet disclosures, and the methods of citation in search reports which are the most helpful for third parties wishing to locate the cited work. © 2012 Elsevier Ltd.

U.S. patent number 1,000,000 was granted on 8 August 1911 to Francis Henry Holton Sr. It appears that the coveted number was coincidentally granted to this largely-forgotten pioneer in the US rubber industry, who had a long history of patenting throughout his working life. He founded a number of rubber businesses on the East Coast of the USA and was later employed by B.F. Goodrich in Akron, Ohio. U.S. 1,000,000 was for a new form of non-pneumatic automobile tyre and was granted to Holton as a private individual when he was long retired and nearly 80 years old. © 2011 Elsevier Ltd.

This article commemorates the centenary of the grant of a key patent in the development of the single-sleeve valve (often referred to as the Burt-McCollum sleeve valve). This emerged as an alternative to the conventional spring-loaded poppet-valve systems in internal combustion engines in automobiles, especially in applications where their smoother and quieter characteristics are significant. The rivalry and litigation resulting from several inventors patenting similar systems at about the same time is described, together with the later application of the single-sleeve valve system to aero engines. © 2010 Elsevier Ltd.
