Special rules of classification within this subclass

In this subclass, three different Indexing Schemes are used:

  • The first Indexing Scheme follows the EC scheme with an identical wording and scope as the corresponding EC scheme. This first Indexing Scheme is used for indexing additional information, thus non-trivial technical information which does not in itself represent an addition to the state-of-the-art, but might constitute useful information for the searcher. The use of this first Indexing Scheme is non-obligatory.
  • The second Indexing Scheme represents a further sub-division of the EC scheme. The symbols of this second Indexing Scheme are hierarchically arranged under, and are in their scope limited by the scope of the respective symbols of the first Indexing Scheme or EC scheme to which they are linked. This second Indexing Scheme is used for indexing both, invention information and additional information. The use of this second Indexing Scheme is obligatory for invention information.
  • The third Indexing Scheme is an Indexing Scheme under the subclass B63B which is used in all subclasses under the class B63 "Ships or other waterborne vessels; Related equipment". This third Indexing Scheme is used for indexing information related to the invention information which is not limited to the scope of one of the main-groups in the class B63. The use of this third Indexing Scheme is obligatory for invention-related information.
