We are delighted to have been ranked again this year as “Leading Firm 2024” in Germany as well as in Europe, Middle East & Africa (EMEA) in the categories “Patent Prosecution” and “Patent Litigation” by LEGAL 500. Thanks to a strong team, we were able to win these special awards.
A special thank you goes out to our clients and colleagues for the great recommendations of our firm:
‘The Prufer team works hand in hand both internally and externally with colleagues in an exemplary manner. They perfectly pass the ball to each other.’
‘Internally, cross-disciplinary questions are discussed quickly and easily and feedback is given. Questions are recorded and answered, regardless of who you ask and whether the contact is an expert or not.’
‘The advice is given on what is best for the client and not on what the client wants to hear.’
‘The overall level of service is excellent. Response is always very quick and appropriate and the ability to understand and analyse legal and technical issues is sufficiently high.’
The ranking can be seen here.
The European Patent Office will increase most of its fees by an average of around 5% as of 1 April 2024. The fee increase will be significantly higher for the 3rd and 4th renewal fees, which will rise by almost 30%.
Renewal fees can be paid to the EPO at the earliest 3 months before the due date. To save money, it would therefore be advisable to pay renewal fees due by 30 June 2024 before 1 April 2024.
You can find the EPO’s complete fee table here.

Dear Sir or Madam,
In view of the digital age, in which documents will only be served electronically in the future, the European Patent Office will abolish its so-called 10-day fiction of service, which previously governed the calculation of time limits, as of November 1, 2023.
With amended Rules 126(2) and 127(2) EPC, the current fiction of service, according to which a document is deemed to have been served on the tenth day after delivery to the postal service provider or – in the case of electronic service – on the tenth day after its transmission (“ten-day rule”), will no longer apply as of November 1, 2023. Instead, a new fiction of service will be introduced, according to which electronic (but also any postal) service will be deemed to have taken place on the date as shown of the document.
The amended service fiction is expected to lead to a simplification for users because it will bring the service rules of the EPC and the PCT more in line with each other.
Do you have any further questions on this topic?
Please contact us, we will be pleased to advise you!

This article was originally published in German on JUVE Handbuch Wirtschaftskanzleien 2022/2023.
The decision of the Enlarged Board of Appeal (GBK) of the European Patent Office (EPO) in the currently pending proceedings G2/21 is awaited with great excitement. This could have a significant impact on the future filing strategy of applicants, because at its core is the question of when an invention is “ready” to file.
Securing an early filing date for an invention is an important aspect of a patent strategy in order to secure one’s own legal position vis-à-vis competitors. For time and cost reasons, the question arises as to how much experimental effort must be expended under patent law aspects before filing a patent application in order to support the claimed effects, or whether corresponding evidence can be submitted subsequently.
Until a decision G2/21 is issued to finally clarify relevant submission questions, this article will discuss practical scenarios that will continue to exist regardless of the answer to the referred questions, but will have to be – possibly re – evaluated with the help of decision G2/21.
Suitability of “evidence” from product development as support of an invention
In the context of a product development, the product of a competitor or the internal ‘gold standard’ is often used as a reference product, regardless of whether the structure or composition of this reference product is known precisely. Such comparative data are often not usable in the context of the ‘problem-solution approach’ applied by the EPO, since, according to established case law, the claimed effect must be clearly attributable to the distinguishing characteristic.
Experimentally investigating the influence of all potentially relevant parameters on the claimed effect and thus exploring the limits of the invention can be time-consuming and financially expensive and usually does not appear to be expedient from the inventor’s point of view.
Irrespective of this, the proof of technical effects can often only be produced with pinpoint accuracy in the knowledge of the objectively closest prior art, e.g. in the examination procedure, since only then will the objectively fitting (because closest to the claimed invention) comparative form be known.
For such reasons, experimental investigations are often postponed to a later point in time. Whether this postponement is possible at all, however, is now to be clarified by the GBK.
Underlying question of G2/21
According to the questions referred, the GBK is primarily concerned with the question of whether evidence such as experimental data must be disregarded only after the patent application has been filed if it constitutes the exclusive evidence for a claimed effect. Three approaches are presented to the GBK, all of which revolve around the criterion of whether or to what extent the information originally provided in the application must render a claimed effect plausible:
The most generous scenario for the applicant would be if the exclusive evidence for a claimed effect could readily be provided after the filing date, i.e., no plausibility requirement at all. This would allow filing an invention in an early, possibly speculative (“immature”) state to secure an early filing date.
However, should the GKB come to the conclusion that minimum plausibility requirements are to be set with regard to the claimed effects in the application itself, a corresponding “ab-initio plausibility” could be applied as a standard for the technical effects.
In a third case, it could be required as a minimum that the claimed effects are at least not implausible from the outset, i.e. that there is no “ab-initio implausibility“.
State of maturity – when is an invention ready to be submitted
Regardless of how the GBK will decide, we always consider it useful to file an application only when advantages over the prior art can at least be named; proof of the technical effects, e.g. by comparative experiments, should be checked before filing.
The “state of maturity” of an invention could be classified as follows:
(i) effects are not (yet) known, only the features characterizing the desired product can be stated.
In this case, if an early filing date is a priority, one could include a “laundry list” of potential effects in the application text, and then pick the desired effect if needed. Although a lack of disclosure does not arise directly from the failure to obtain effects from the application as long as they are not reflected in the claim wording, an entirely speculative invention description could, in some circumstances, call into question the consideration of late evidence or even reworkability.
(ii) Effects are expected and the features of the invention that are causally responsible are suspected.
Here, the expected effects can already be specifically named; these should then at least not be “ab-initio implausible”. From a technical point of view, no doubts should be justified against the possible achievement of the named effects. In the description of the invention in the original application, the challenge is that it is not known which features/parameters are causal for the achievement of the effect. Regardless of decision G2/21, if possible, the “causality” between effects and the corresponding features of the invention should be investigated and explained in the application text. Previously published literature can help to substantiate this causal relationship. Patent law only requires that something works or that a set task is solved; a scientific explanation of how a claimed problem solution works is not necessarily required.
(iii) Effects are expected, it can be concluded on the basis of technical considerations which features of the invention should be causally responsible for them.
A technical explanation that the claimed effects are expected can be given in the patent application (“ab-initio plausibility”). However, a real experimental proof is still missing. In such a case, the prospects of grant – assuming the required novelty – are likely to be good, but it is to be expected that e.g. in possible opposition proceedings the opposing party could attack this “plausibility”, e.g. by submitting reasonable doubts that the theory underlying the plausibility is not correct. Without wanting to anticipate the final decision in the current referral G2/21, however, it should be possible in these case constellations on the basis of the existing “ab initio plausibility” to substantiate the expected technical effects in the factual instance – i.e. not only in appeal or appeal – by means of subsequently supplied experiments and data.
(iv) Effects are known and proven
Here, there should be nothing to argue against filing a patent application. If new prior art is invoked, e.g. in the examination procedure, it should be possible to provide further (post-published) experimental data to support the effects already shown in the application, if required.
Special cases
Special cases exist if technical effects are only proven or expected for a part of a claimed subject-matter, or if a technical effect itself constitutes a claimed feature – e.g. in a use claim. In the first case, the question then arises whether the technical effect can plausibly be generalized to the remaining part of the claim, and in the second case the criterion of “plausibility” will also be relevant in the context of examining whether the invention is sufficiently disclosed at all and thus practicable. Here, too, however, considerations similar to those explained earlier should play a role.
Conclusion
• The decision of the GBK in the proceedings G2/21 will hopefully provide clarity as to the “state of maturity” in which an invention must be filed in order for claimed effects to be recognized.
• In many cases, regardless of the standard to be applied under G2/21, early submission will be desired.
• It is already apparent that the question of “plausibility” does not constitute a patenting requirement in its own right, but is an important criterion in the examination for inventive step and possibly even the practicability of a claimed invention.
• In any case, it is wise to check the maturity of the invention before filing a patent application in order to achieve the best possible result and obtain a strong patent.

On July 15, 2022, Montenegro completed the final step towards accession to the European Patent Convention (EPC) by depositing its instrument of accession and became the 39th member state of the European Patent Organization (EPO) on October 1, 2022.
This means that Montenegro is leaving its status as an extension state, which it obtained in 2010, and all patent applications filed on or after October 1, 2022, can be validated as a European patent with effect for Montenegro once they have been granted.
The official admission of Montenegro as a member state is a new milestone in the history of the European Patent Organization.
