British patents listed by Patentee
When
a patent application was received it was given a filing number, until the start of 1916 this number was the number by which the patent was known. Each year the number sequence started again from 1, so to identify a patent the number and year of filing is needed. The highest number reached in any year was 31000. From 1916 the system was changed, the patent number (known as the serial number) was issued at the end of the process and ran contiguously starting at 100,001 and did not re-set each year. When a patent was filed it was still given a filing or application number which did re-start from 1 each year. Between the initial filing or application and the final granting of the patent the filing number may be used to identify the patent. So a number lower than 100,000 may be a patent issued before 1916 or a filing number issued from 1916. Prior to 1852 patent numbers ran contiguously rather than per year and were the filing number.
There are several dates associated with a patent: Initial filing, often a provisional specification would be submitted at this time and a filing number would be allocated; Full Specification provided, generally 6 to 12 months following the initial filing; Patent Published, the serial number is issued (from 1916), generally 15 - 24 months from initial filing. Under the Paris Convention of 1883 foreign patents can use the original date of filing in their own country. These are identified with words like "date claimed under convention".
The modern representation of a patent number is GB999999[yyyy], in earlier years there was no recognised format though 9999/yy is common. Before 1916 the year given is the date of initial filing, after this, the date used is generally the date of publication.
Unlike in many countries, in Britain there was no check made by the patent office for novelty or originality, it was not until around 1905 - 1907 that an examiner made such checks.
Prior to 1919 British patents lasted for 14 years from the time of initial filing, after this until recent times they lasted 16 years. For further information see Stephen van Dulken. "British Patents of Invention, 1617 - 1977. A Guide for Researchers"
