The Market Court: An Apparatus and Method for Treating Pulp Does Not Involve an Inventive Step

The Market Court issued a patent decision 454/16 on 21 July 2016. The court ruled that the applied invention (Apparatus and method for treating pulp) is not patentable because the patent claims do not involve an inventive step. As a result, the court ordered PRH to revoke the patent FI 122775.

Background

Andritz Oy (Andritz) sought patent protection on its invention called "Apparatus and method for treating pulp" on 7 September 2004. The application consisted of two independent claims (1 and 15) and dependent claims 2-14 and 16-24. The Patent and Registration Office (PRH) granted a patent for the invention (FI 122775) on 29 June 2009.

FI 122775, Figs. 1a-1b.


Metso Paper Sweden AB (Metso) lodged an invalidation claim against the patent. During the invalidity proceedings at PRH, Andritz filed amended claims first on 16 October 2013 and later on 12 May 2014. PRH granted a patent for the invention on 1 December 2014 in accordance with the amended claims provided on 12 May 2014 (independent claims 1 and 12 and dependent claims 2-11 and 13-21).

Later on, the company name Metso was changed to Valmet AB (Valmet).

Valmet did not agree with the decision of PRH and lodged an appeal at the Market Court. Valmet requested the Market Court to reverse the decision of PRH.

The Market Court

According to section 1 paragraph 1 of the Patents Act (550/1967), anyone who has, in any field of technology, made an invention which is susceptible of industrial application, or his or her successor in title, is entitled, on application, to a patent and thereby to the exclusive right to exploit the invention commercially, in accordance with this Act.

According to section 2 of the Act, patents may only be granted for inventions which are new in relation to what was known before the filing date of the patent application, and which also involve an inventive step with respect thereto. Everything made available to the public in writing, in lectures, by public use or otherwise is considered to be known.

According to section 25 paragraph 1 of the Act, the Patent Authority shall revoke a patent on account of an opposition [inter alia] if the patent relates to an invention that does not satisfy the requirements of sections 1 and 2.

The Applied Claims

The independent claims 1 and 12 (translated with the help of CA2578004 A1):

1. An apparatus for treating pulp, said apparatus comprising at least one liquid-permeable surface rotating around a shaft, onto which surface a pulp layer is formed, means for feeding the pulp being treated into the apparatus, means for discharging the treated pulp from the apparatus and means for removing filtrates from the apparatus, characterized in that the apparatus is provided with at least one inside construction for forming at least two treatment sections in the apparatus in such a way that each of the sections is connected to means for feeding at least one pulp so that the pulps treated in the sections come from essentially different treatment stages and to pulp removal means so that the treated pulps are removed from the apparatus separately, whereby the apparatus comprises a first and a second treatment section, the pulp feeding means of the first thereof being connected to a first treatment stage with first treatment conditions and the pulp feeding means of the second thereof being connected to a second treatment stage with second conditions.

12. A method for treating pulp, in which method the pulp is fed onto a liquid-permeable surface rotating around a shaft of the treatment apparatus, onto which surface a pulp layer is formed, wherefrom liquid is removed, and the treated pulp is removed from the apparatus, characterized in that a first layer of pulp is formed on the rotating surface, said pulp coming from a first treatment stage, and in a distance from the first layer in the longitudinal direction of the shaft a second pulp layer is formed, said pulp coming from a second treatment stage, and the pulp layers are treated essentially separately from each other.

Prior Art

The prior art in this case consists of the following documents:

O1: US 5641402
O2: US 5275024
O3: WO 92/22703
O4: US 4551248.

Novelty and Inventive Step

The court stated that the drum filter defined in the applied invention is new compared to the solutions defined in the prior art. 

The court then moved on to assess the inventive step regarding the claims 1 and 12.

The court considered that the apparatus described in the claim 1 and the apparatus described in the prior art O1 have only one difference: the former is describing a drum filter whereas the latter is describing a disc filter.

The court stated that the invention described in the O1 is solving the same problem as the drum filter described in the claim 1 of the applied invention. The court also stated that, according to the description of the O1, the disc filter and drum filter are alternatives regarding apparatus for treating pulp in the pulp and paper industry.

According to the court, the use of drum filter does not require any particular technical solution. Consequently, it is considered to be obvious to the person skilled in the art. The technical solution defined in the claim 1 does not involve an inventive step.

The method described in the claim 12 comprises the same technical features as the apparatus described in the claim 1. Consequently, this claim does not involve an inventive step, either.

The invention is not patentable.

As a result, the court returned the case to PRH and ordered PRH to revoke the patent FI 122775.

FI 117912, Fig. 2.

Miratel Oy (Miratel) lodged an invalidation claim against the patent, but PRH dismissed the invalidation claim on 6 May 2008. Miratel then lodged an appeal at the Board of Appeal at PRH. The Board of Appeal accepted the invalidation claim and returned the case to PRH on 14 October 2011. PRH revoked the patent on 17 February 2012. According to PRH, the independent and dependent claims do not involve an inventive step.

Later on, the company name Exrei was changed to Everon Ab (Everon) and Miratel into Ascom Miratel Oy (Ascom Miratel).
  
Everon did not agree with the decision of PRH and lodged an appeal at the Market Court. Everon requested the Market Court to reverse the decision of PRH. 

Furthermore, according to Everon, the patent application should be accepted in accordance with the claims that were under examination in the decision of PRH or, if that is not possible, in accordance with the claims attached into the appeal (independent claims 1, 17 and 33 and dependent claims 2-16, 18-32 and 34-35).

The Market Court

According to section 2 of the Patents Act (550/1967), patents may only be granted for inventions which are new in relation to what was known before the filing date of the patent application, and which also involve an inventive step with respect thereto. Everything made available to the public in writing, in lectures, by public use or otherwise is considered to be known.

According to section 8 paragraph 2 of the Act, the application shall contain [inter alia] a precise statement of the subject matter for which patent protection is sought.

According to section 13 of the Act, an application for a patent may not be amended in such a way that protection is claimed for matter not disclosed in the application at the time it was filed.

According to section 25 paragraph 1 of the Act, the Patent Authority shall revoke a patent on account of an opposition [inter alia] if the patent relates to an invention that does not satisfy the requirements of section 2, or if the patent contains subject matter not included in the application as filed.

Prior Art

The prior art in this case consists of documents D1-D20 (a list with document names can be found in the decision). However, the court decided to dismiss the D4 because its publication date was not unambiguous.

The Original Patent Claims

The independent claims 1, 21 and 41 (translated with the help of US 20090016511 A1):

1. A method for relaying and managing service calls, wherein a customer terminal sends a call and a service terminal receives an assignment, characterised by transmission of the call information from the customer terminal to the server (120), in which the server-based data on the service providers comprise data for establishing a connection to the service provider's service terminal and additional service provider data, whereby a call arriving at the server activates the server's selection of a service provider on the basis of the data contained in the call (130) and said additional data (140), and to send an assignment based on the data of the call to the service terminal (150) in accordance with the contact information of the selected service provider.

21. A system for relaying and managing service calls that comprises customer terminals (230, 250) for sending calls and service terminals (270) for receiving assignments that is characterised by the system comprising a server (210) that has memory (214) for storing the information of the service providers, which comprises data for establishing a connection to the service provider's service terminal (270) and additional service provider data, with the system further comprising the means (212, 230-250) for relaying the call data from a customer terminal (230, 250) to the server (210), whereby the server is arranged to be activated on the incoming call and perform selection of a service provider on the basis of the data contained in the call and said additional data, and to send an assignment based on the data of the call to the service terminal (270) in accordance with the contact information of the selected service provider.

41. A server (210) for relaying and managing service calls in a system that comprises customer terminals (230, 250) for sending calls and service terminals (270) for receiving assignments, characterised by the server having memory (214) for storing the information of the service providers, which contains data for establishing a connection to the service provider's service terminal and additional service provider data, with the server further comprising the means (212) for receiving call data from a customer terminal, whereby the server is arranged to be activated upon the incoming call and select a service provider on the basis of the data contained in the call and the said additional data, and to send (216) an assignment based on the data of the call to the service terminal in accordance with the contact information of the selected service provider.

The court considered that all the features of the independent claim 1 are found in a prior art D1a. The D1a is an issue of a customer magazine produced by Ascom Miratel. The D1a introduces a software called CareWin. The software is used to receive safety calls and alarms. This software is, according to the court, a method for relaying and managing call messages, in which a customer terminal (safety phone) sends a call and a service terminal (caretaker of a person responsible for the service) receives an assignment and in which there is a transmission of the call information from the customer terminal to the server (CareWin-software).

The court then stated that the independent claims 21 and 41 consist of the same technical features as defined in the claim 1.

The court concluded that the independent claims 1, 21 and 41 are lacking novelty and they do not involve an inventive step. 

The Secondary Patent Claims

The independent claims 1, 17 and 33 (translated with the help of US 20090016511 A1, the changes are written in red):

1. A method for relaying and managing service calls, wherein a customer terminal sends a call and a service terminal receives an assignment, characterised by transmission of the call information from the customer terminal to the server (120), in which the server-based data on the service providers comprise data for establishing a connection to the service provider's service terminal and additional service provider data, whereby a call arriving at the server activates the server's selection of a service provider on the basis of the data contained in the call (130) and said additional data (140), whereby the said additional data comprising data concerning the services provided by the service provider, whereby the selection of the service provider will be based at least on the call- contained data concerning the service need and said additional data on the services provided by the service provider, and to send an assignment based on the data of the call to the service terminal (150) in accordance with the contact information of the selected service provider, whereby the method includes 
- the server comprising a log memory for storing data pertaining to calls that have arrived and/or assignments sent,  
- storing an acknowledgement saved on the server concerning the reception of an assignment by a service provider and/or an acknowledgement for the completion of a service and 
- invoicing the customer for the services on the basis of said log data.

17. A system for relaying and managing service calls that comprises customer terminals (230, 250) for sending calls and service terminals (270) for receiving assignments that is characterised by the system comprising a server (210) that has memory (214) for storing the information of the service providers, which comprises data for establishing a connection to the service provider's service terminal (270) and additional service provider data, with the system further comprising the means (212, 230-250) for relaying the call data from a customer terminal (230, 250) to the server (210), whereby the server is arranged to be activated on the incoming call, whereby the said additional data comprising data concerning the services provided by the service provider, whereby the selection of the service provider will be based at least on the call- contained data concerning the service need and said additional data on the services provided by the service provider, and perform selection of a service provider on the basis of the data contained in the call and said additional data, and to send an assignment based on the data of the call to the service terminal (270) in accordance with the contact information of the selected service provider;
-whereby the said server of the system includes 
- a log memory for storing data pertaining to calls that have arrived and/or assignments sent, 
- means (214, 218) for storing an acknowledgement saved on the server concerning the reception of an assignment by a service provider and/or an acknowledgement for the completion of a service and 
- means (214, 218) for invoicing the customer for the services on the basis of said log data.

33. A server (210) for relaying and managing service calls in a system that comprises customer terminals (230, 250) for sending calls and service terminals (270) for receiving assignments, characterised by the server having memory (214) for storing the information of the service providers, which contains data for establishing a connection to the service provider's service terminal and additional service provider data, with the server further comprising the means (212) for receiving call data from a customer terminal, whereby the server is arranged to be activated upon the incoming call, whereby the said additional data comprising data concerning the services provided by the service provider, whereby the selection of the service provider will be based at least on the call- contained data concerning the service need and said additional data on the services provided by the service provider, and select a service provider on the basis of the data contained in the call and the said additional data, and to send (216) an assignment based on the data of the call to the service terminal in accordance with the contact information of the selected service provider;
-whereby the said server of the system includes 
- a log memory for storing data pertaining to calls that have arrived and/or assignments sent, 
- means (214, 218) for storing an acknowledgement saved on the server concerning the reception of an assignment by a service provider and/or an acknowledgement for the completion of a service and
- means (214, 218) for invoicing the customer for the services on the basis of said log data.

Ascom Miratel argued first that the claims are amended in such a way that protection is claimed for matter not disclosed in the application at the time it was filed. Furthermore, Ascom Miratel argued also that the amended application does not contain a precise statement of the subject matter for which patent protection is sought. The court dismissed these arguments.

Now it was time to assess whether the invention, in the form of the secondary claims, is new in relation to what was known before the filing date of the patent application, and also involves an inventive step. 

The secondary claim 1 defines, inter alia, how the server comprises a log memory for storing data pertaining to calls that have arrived and/or assignments sent and how the invoicing is based on the log data. The prior art D1a does not contain any information of storing data pertaining to calls that have arrived and/or assignments sent. Therefore, according to the court, the invention defined in the claim 1 is new in relation to the prior art D1a.

However, the court stated that the description of the invention does not explain any technical effect achieved based on the type of data stored and the type of log data used in the invoicing. The description only explains that the method is solving a problem regarding the automation. The court then added that also the method defined in the prior art D1a is automatized.

The court then stated that it would be obvious for the person skilled in the art to use the stored call and/or assignment data in invoicing. The person skilled in the art also understands that the software introduced in the prior art D1a might comprise a feature, or it is possible to add such a feature into the software, in which data, pertaining to calls that have arrived and/or assignments sent, is used.

Therefore, according to the court, the invention defined in the secondary claim 1 does not involve an inventive step.

The court then stated that the secondary claims 17 and 33 comprise the same technical features as the secondary claim 1. Consequently, these claims do not involve an inventive step, either.

The invention is not patentable.

The action is dismissed.
