CHEMICAL STRUCTURE PATENT SEARCH

Chemical structure patent searches are conducted by scientists, chemistry patent attorneys, health-professionals, chemists, professionals in the pharmaceutical industry, in-house chemical lawyers and pharmaceutical attorneys.

Many chemical compounds which form subject matter of patent claims are available in the patentscope WIPO database. However, to search relevant patent results, a proper chemical structure patent search strategy should be formed. Researching accurate patent chemical compounds is a daunting task if the chemical structure patent search strategy is not in place. In this chemical structure patent article we will cover a list of checklists to be taken in consideration while performing chemistry based searches. The checklist will be helpful for chemical patent lawyers or pharmaceutical patent attorneys. Whether you are working on patent infringement suit involving chemical compounds or a patent  due diligence project for an acquisition, determining the true value of granted chemical patent will be helpful in the long run.

Chemical Structure Patent Search for a Molecule

Step 1: Identify key features of the technology based on the information provided.

Step 2: Identify the main independent claims of the granted patent.

Step 3: Identify alternative names of the main chemical compounds including trivial name, commercial name, IUPAC name or CAS name, the International NonProprietary Name, INN InchI, InchIkeys and  Smiles.

Step 4: Identify different spellings of chemical names.

Step 5: Chemical structure research can be carried out in WIPO(patentscope), ChemSpider and Surechembl.

Case Study Example: Chemical patent chemical compound search for mannitol

Alternative names and structure details for Mannitol

You can search the patent chemical compounds using the above mentioned patent databases. The patent results can be narrowed down with other relevant keywords and/or IPC, CPC, USPC. If you are an independent chemical researcher searching by compound name will not be useful because related structural analogs will have unrelated names. Therefore to find results covering analogs of chemical compound, you need to perform a chemical structure search in patent databases.
