Patent Applicants Encode Sequence Information for Submission
Note:
Many patent applicants generate and encode sequence information in computer readable form to facilitate submissions or research.

In those areas of biotechnology in which nucleotide and/or amino acid sequence information is significant, many patent applicants are accustomed to, or familiar with, the submission of such sequence information, in electronic form, to various sequence databases, such as GenBank, which is produced by the National Institutes of Health. In order to facilitate such submissions, or merely for the purpose of researching and developing sequence information, many eventual patent applicants also generate or encode sequence information in computer readable form. In order to further facilitate compliance with the sequence rules, the Office previously made available to the public an input program based on the AuthorIn program produced by GenBank. This input program, called PatentIn version 1.3, was specifically tailored to the requirements of the sequence rules which were in effect between October 1, 1990 and July 1, 1998. Applications filed in the U.S. or in member countries of WIPO after July 1, 1998, containing sequence listings prepared using PatentIn version 1.3 will not be in compliance with 37 CFR 1.821 – 1.825 or ST.25.

PatentIn Version 1.3 for Sequence Listings

The Office provided an input program, PatentIn version 1.3, tailored to the sequence rules from October 1990 to July 1998 for preparing sequence listings.

Requirement for Sequence Listing Format
Note:
The sequence listing format used in PatentIn version 1.3 was required for applications filed between October 1, 1990 and July 1, 1998.

Sequence Listing Rules Effective July 1998
Note:
The rules for sequence listings, effective since July 1998, outline the format requirements for patent applications.

The current sequence rules, which are embodied in 37 CFR 1.821 – 1.825 and World Intellectual Property Organization (WIPO) Standard ST.25, became effective July 1, 1998. Several versions of PatentIn have been released since 1998.

PatentIn Program Recommended for Sequence Listings
Note:
The use of the PatentIn program is recommended for generating sequence listings, as it reduces errors and eases the generation process compared to manual creation.

While use of the PatentIn program is not required for compliance with the sequence rules, its use is highly recommended, as Office experience has shown that submissions developed with PatentIn are far less likely to include errors than those developed without the program. The many automatic features of the PatentIn program also greatly ease the generation of a “Sequence Listing” when compared to generating them by hand in a word processing environment. This is especially true for a “Sequence Listing” that includes many sequences and/or sequences having great lengths.
