Meera, a researcher at a Pune firm, wants to find all published patent documents on lithium-ion battery separators using a worldwide classification scheme (IPC) that groups inventions into sections, classes, subclasses and groups. Which statement best describes how such a hierarchical classification helps her search?

Classification lets a searcher locate patent documents by technical subject matter regardless of the wording used. It organises inventions into sections, classes, subclasses and groups. It does not show legal validity or force in India, nor does it replace reading the claims.

  1. AIt lets her search by technical subject matter irrespective of the language or wording used by the applicantCorrect
  2. BIt lets her search only by the applicant's name and nationality
  3. CIt guarantees that every document found is valid and in force in India
  4. DIt removes the need to read the claims of any document found

Explanation

A hierarchical classification (section, class, subclass, group) assigns documents to technical fields, so a searcher can find documents by subject matter regardless of the words used. It does not search by applicant name, confirm validity, or replace reading the claims.
