New Zealand accession dates for US patent specifications


This information has been taken from IPONZ’s past collection of US patent specifications. The data include the range of patent numbers which have been received by paper, microfilm or CD and the date that the film was made publicly available in New Zealand.

The collection covers patent specifications for the periods: 1940-1947 and 1961-2007. The years 1948 - 1960 have not been recorded as they were not able to be located.

IPONZ stopped receiving US Patent Specifications after August 2007. Accession dates after this time are determined by:

  1. the date the patent was published on the US website, or
  2. one month after the above
