As a first step, using the advanced search option (found in the drop-down menu “search”), you can insert and combine the most relevant keywords (separated by a space) in the search fields for the technology you are interested in, e.g. sparkling, beer, etc. (you can also use inverted commas “” to find an exact phrase).
A complementary means of searching existing patents is to use the International Patent Classification (IPC), according to which patents have are divided into specific technical groups. All you need to do is enter a keyword to try the IPC search.
Whilst our online searches are helpful, we would always advise you to seek further information from your national patent or intellectual property office or from an intellectual property professional. Consult our list of intellectual property offices.
Also please keep in mind that patent applications are generally not filed for a complete commercial product. Final products usually incorporate many separate innovations by different inventors. Indeed, the product may even contain technologies for which no patent application has ever been filed.
A sequence listing is a part of a patent application that contains detailed description of the nucleotide and/or amino acid sequences in the application.
