DNA / RNA and Protein Sequencing

Sequence Listing

According to the U.S. and foreign Sequence Listing requirements under WIPO ST.25 and 37 CFR 1.821- 1.825, a Protein sequence should be an unbranched sequence of four or more naturally occurring ‘specifically defined’ L-amino acids, and in the case of DNA or RNA sequences, it is an unbranched sequence of ten or more nucleotides, in which at least 4 nucleotides need to be ‘specifically defined’.

Preparing a valid Sequence Listing with these restrictions and regulations can be very time consuming and is prone to inconsistencies.  With our trained and dedicated staff, we are able to give you the edge and assist you in identification and creation of sequence listings that are consistent and complete.

The computer readable form of the sequence listing that we prepare for you is acceptable for all receiving Offices of WIPO, International Searching and Preliminary Examining Authorities for the purposes of the international phase, and to all designated and elected Offices for the purposes of the national phase.

Sequence Searching

With the continual growth found in a wide variety of chemistry and chemical engineering technology domains including pharmaceuticals, detergents, paints, polymers and plastics, adhesives, ceramics, fertilizers, textiles, printing inks, paper making, petroleum, cement, metallurgy, and other general chemicals, the need to perform chemical patent searches for Novelty/Patentability, Validity/Invalidity, Freedom to operate, or Infringement search steadily increases. 

The scope of your search is customized to your needs, which may range from concept based keyword search to complex chemical compound searches.  Then by tailoring to your particular search requirements we identify the correct database and the precise search method.

For a chemical compound search we are careful in choosing the best possible way to make it effective and efficient, whether it is by the chemical name, molecular formula, molecular weight, physical properties, uses, registry number, structure, and/or whether your com-pound is a reactant or a product.

For focused Chemical compound searches, we use STN to access CAPLUS, CAS Registry, MARPAT, BEILSTEIN and WPINDEX.  With the help of MARPAT database we explore through claims and patent disclosures to find the generic Markush Chemical Structures. We also have the choice of Micropatent for patent search.
