1.1 Analysis of the application 

The search division first of all studies the application to determine the subject-matter of the claimed invention (see B‑III, 3) and critically analyses the claims in the light of the description and drawings to establish whether they are potentially open to any objection. In particular, it studies the content of the claims, description and drawings in enough detail to identify the problem the invention is intended to solve, the inventive concept leading to its solution, the features essential to the solution, as found in the claims, and the results and effects obtained (see, however, B‑III, 3.5). If, according to the description, technical features not included in the claims are essential to solving the stated problem, these features are included in the search (see F‑IV, 4.3(ii) and T 32/82).
