Reasons for the Decision 1. Consideration of documents filed for the first time in appeal proceedings 1. These documents were filed in response to the reasoning in the impugned decision.

None of the parties objected to the admission of these documents into the proceedings and the board itself also has no concern against taking these documents into consideration. D31 concerns a judgment of a UK court on the validity of D32, a case having a priority date from ; the purpose of these documents was to show the common general knowledge of the skilled person in However, common general knowledge develops over time, and it cannot be concluded that these documents are relevant for establishing the common general knowledge of the skilled person at the priority date of the contested patent in Documents D33 to D35 are scientific articles and an expert opinion concerning XRD measurements and texture coefficients.

In combination with D31, which itself makes already reference to various expert opinions, these documents, presented at a late stage in the appeal proceedings, increase the complexity of the case to such an extent that the board and the other parties could not be reasonably expected to deal with them at the oral proceedings.

By exercising its discretion pursuant to Article 13 1 and 3 RPBA the board therefore does not admit documents D31 to D35 into the proceedings. Procedural defects of the opposition proceedings 2. The minutes of the oral proceedings before the opposition division do not mention any discussion or decision on the admission of these late filed documents into the proceedings, nevertheless they are cited and taken into account in the impugned decision see points 1.

Therefore it has to be concluded that the appellant, then patent proprietor, did not get an opportunity to discuss the admission of documents D22 and D23 into the proceedings before the decision on their admission was taken, contrary to the requirements stipulated by Article 1 EPC.

The first examiner explained what the problem was.

The opposition division refused the adjournment of the oral proceedings. The board considers that in the present case the refusal of the adjournment constitutes an unfair treatment of the appellant since the appellant did not have an appropriate opportunity during the oral proceedings to prepare a proper defense against this new objection.

Accordingly, as the appellant could not present its comments on the ground on which the decision was based, the appellant's right to be heard pursuant to Article 1 EPC was violated. The refusal of the adjournment is justified in point 1.

The opposition division pointed out that further data could have been filed earlier and would in any case not have been suitable for supplementing the insufficient information in the contested patent. The board in principle agrees that further data cannot necessarily supplement the insufficient information in a patent.

However, according to page 1, 4th paragraph of the minutes the appellant asked for time to provide further information, not just data, to support its arguments. Further information on the common general knowledge of the skilled person can demonstrate that information not explicitly disclosed in a patent specification nevertheless is known to the skilled person, since it belongs to the common general knowledge.

Therefore the reasoning of the contested decision does not take into account the arguments presented by the appellant as indicated in the minutes. Moreover, the appellant had no reason to expect that further information on the common general knowledge was needed at the oral proceedings, since it was not aware of the objection before the oral proceedings, in particular, since the objection raised by the opposition division is based on document D21, submitted by the appellant in preparation of the oral proceedings in a different context.

However, according to the minutes of the opposition division , sufficiency had not been discussed in light of D16 during the oral proceedings. Nor can the board identify in the written submissions of the then opponents the line of argument later presented in the impugned decision. This amounts to a further violation of Article 1 EPC. Furthermore, it was not made aware of the essential legal and factual reasons, that lead to the revocation of its patent, before the decision was taken.

As a causal link between these procedural defects and the decision is clearly given, these defects qualify as substantial procedural violations. Against the background that the respondents had no objections in this regard and the issue of sufficiency of disclosure was discussed in detail in the written submissions of the appeal proceedings, the board did not remit the case pursuant to Article 11 RPBA and considered the issue of sufficiency of disclosure in accordance with Article 1 , second sentence, EPC.

Article b EPC 3. The board considers it more appropriate firstly to evaluate whether the skilled person is put into position to achieve a cutting tool insert comprising an alpha-Al2O3 layer with a strong texture, before going on to assess the ability to determine whether the texture coefficient as defined in claim 1 is met.

The contested patent starts from this knowledge of the skilled person and proposes a cutting tool comprising an alpha-Al2O3 coating having a strong texture as defined by the TC in claim 1. According to the last two sentences of paragraph [] of the contested patent, a strong texture in orientation was unknown at the priority date of the contested patent and can only be achieved when both, nucleation and growth are controlled correctly.

Therefore according to the contested patent the skilled person was aware that different grain orientations could be obtained when depositing an alpha-Al2O3 layer, but was not aware of a method of manufacturing an alpha-Al2O3 layer having a sufficient high amount of the required texture as expressed by the TC value defined in claim 1. The board observes in this context that the contested patent does not provide any detailed teaching concerning the apparatus and the specific conditions of the various coating steps, such as the composition of the gas mixture, gas flow, duration and pressure, which can be used to manufacture the cutting tool insert defined in claim 1.

In particular, no detailed example is presented which guides the skilled person to achieve the required texture of the alpha-Al2O3 layer. The appellant confirmed during the oral proceedings before the board, that the orientation of the deposited alpha-Al2O3 differs from apparatus to apparatus. Closely connected to this is the Peierls instability.

In this phase transition, the metallic conducting crystal becomes a semiconductor on cooling below the phase transition temperature Tp. Me refers to a methyl group, I and Br to an iodine or bromine atom; compare the image of the crystal structure in Fig.

The crystal structure is very similar in all cases. The conductivity ranges from the organic metals down to the lowest temperatures upper curve to semimetallic semiconductors the two lowest curves; one of them refers to an alloy. For details see Sect. In addition, these materials are particularly interesting owing to their enormous variability. The organic chemist can furthermore prepare molecules with a wide variety of properties in almost unlimited variations.

Can one thus tell the chemists which molecule they should synthesize in order to produce a new semiconductor, or how a molecule is to be constructed in order to obtain a new superconductor with a high transition temperature?

These are two of the problems which are currently key issues in the solid-state physics of organic molecular crystals. Such problems are often considered with a background of possible technical applications in mind.

An especially important and typical property of molecular crystals is the existence of excitonic states, in some cases with long lifetimes. These are neutral electronic excitation states with an excitation energy which is smaller than the energy required to excite an electron from the valence band into the conduction band, i. One can also speak of an 13 1 Introduction Fig.

In the region between K and 20 K its electrical conductivity varies by 14 orders of magnitude. The temperature ranges A, B, C and D denote four different mechanisms of electrical conductivity. In the range C, the activation energy is constant.

In the range D, the conductivity of the semiconductor is limited by thermal activation of charge carriers from defect states. See Sect. As a rule, the excitation energy of excitons in molecular crystals is so much smaller than the energy required to produce a nonbound electron-hole pair, that is a free electron in the conduction band and a free hole in the valence band, that thermal ionisation of the excitons cannot take place even at room temperature.

When the quantum energy of the photons is not too great, the photo-excitation in molecular crystals thus does not produce free charge carriers, but rather bound electron-hole pairs, in which the distance between the electron and the hole is small in comparison to that of the so called Wannier excitons, excitations below the conduction band in the inorganic semiconductors.

They are termed Frenkel excitons and can be used to store and transport electronic excitation energy, i. Molecular crystals can in this case be used as model substances for the 1. Photosynthesis, the mechanism of sight, and questions of molecular genetics are among these. The organic solids are also interesting as highly nonlinear optical materials and as highly and nonlinearly polarisable dielectrics, as electrets, as ferroelectric materials and as photoelectrets.

In electrets, a macroscopic polarisation is present due to a macroscopic orientation of permanent dipole moments of the structural elements: the solid has a positive and a negative end.
