Monday, November 23, 2020 T 1631/17 - Not-explicit claim features cause exception to patentability

The invention relates to a  method of making dental prostheses using settable dental prosthetic material. The method is more efficient than existing methods since an impression is used of a human denture in which missing tooth substance is supplemented. 

Although not claimed, typically one would first provisionally repair the teeth and take an impression of the "finished" denture. In this way the desired external shape of the denture can be designed directly by the dentist on the patient and the production of the denture parts by the dental technician can be simplified considerably.

Even if not explicit, the Board considers that the claim still encompasses a surgical step, and so is excluded from patentability. 

The decision is in German. Below an machine translation of part of the decision is given, and below that a more extensive selection of the original German. 

Friday, February 19, 2016 T 475/12 - Medical examination may be a treatment

Camera unsuitable for in-vivo use

Can a method or examination become a treatment just because some of its steps may have a therapeutic effect? Claim 1 of the main request is a medical examination method that comprises administering a laxative to a subject, before the subjects swallows an in-vivo imaging device.

According to the applicant the laxative enables a better collection of data through the in-vivo imaging device. Administering the laxative should not be seen as a therapeutic step.

The board has a different opinion. If the subject happens to have constipation, the examination method might be therapeutic. Moreover, the laxative may prevent complications.

The applicant tries to save the claims by inserting the word non-therapeutic, but the Board does not accept this either (see the end of the decision).

Friday, December 11, 2015 T 2369/10 - Second medical use of products

Medical Instruments

The applicant found a new medical use for an existing product; namely treatment of substance addiction using a neurostimulator.
 
Normally a product is not made novel merely by identifying a new use for the product. Although, a use claim or a method claim may be possible, a purpose limitation for a product must imply technical differences in the product itself for it to be novel. 

However, if the new use is a medical one, the option of method and use claims are blocked by article 53(c) EPC, which forbids patenting of medical methods (see the articles for details). Fortunately for medical researchers, an exception is made to the general rule;  a new medical use for "any substance or composition" will provide novelty (articles 54(4), 54(5) EPC, G 5/83).

But what if someone invents a new medical use for a product which is not a substance or composition? The possibility of a method or use claim is blocked by article 53(c) EPC.  The lack of novel technical differences blocks the product claim. Although, article 54 does not explicitly allow the application to products which are not substance or composition, it is not forbidden either. 

The board declined the invitation though, and ruled that no novelty is obtained by a medical purpose limitation if the object is not a substance or composition. A request to  refer questions to the Enlarged board was denied. 

No Catchword or headnote is provided but reasons 8.1 give the following summary.

In the present case, the Board holds that, having regard to the wording of Article 54(4),(5) EPC, the ordinary meaning of this Article shall not be extended so as to include something which is not explicitly provided for.

Consequently the Board considers that there is no basis to contemplate that novelty may be conferred on products, other than substances and compositions, by virtue of the provisions of Article 54(4),(5) EPC.
