interpreted the term regulate data flow and manner that is inconsistent with the prosecution history and rd it misconstrued the term unique identity by holding that the unique identity need not be associated with a particular base station specifically appealed the institution decision and not the final written decision that the holding it or the the panel stated holding in the st paragraph it states we find no error in the board's obviousness determination and the board and nineteen which covers the appeal ability of a final written decision nor does it address three hundred and fifteen e which covers the stoffel impact of a final written decision for real parties interest our position that this case did not address the specific issue we are appealing similarly thrive does not cover either you or does not govern because the rod specifically addresses the time bob provision the three  talent in a case such as this in every single case simply say well i'm appealing not just from the institution decision but from the final written  in your rich and fine written to decision that there is a violation of the real party and just requirement what is it your position that that would then be enough to make a difference the final written decision and the statute on ambiguously says that a party dissatisfied with the board's final written decision quote may appeal the decision and there is no clarifying language in section three hundred and nineteen i think institution decision to be appealed it any analysis in the final written decision is appealable under the statute and east it doesn't address that question so i understand your honour's concern about parties just just saying we're appealing the final written decision but there is an ongoing obligation to update real party and interest throughout a proceeding and the flipside of that argument is that it leaves analysis in the board's final written decision that can't be instituted the remedy would be to order the board to correct its final written decision and state that samsung and verizon are real parties in interest i'm not sure we can go back to the  that's a separate question your honor and that's that part is not appealable your theory is that a board decision real party interest wouldn't affect the institution but that it would affect  specifically mention the final written decision so this is this is something that impacts the real party interest question is something that is impact that impact the final reading decision and impact moving forward in later proceedings as well so this is not something that just tied to the institution decision ok unless my colleagues have further questions on this part of it to be returned to the claim construction yes charlotte let me start with the regulate what do you mean by regulating data flow through the gate i'm not sure that there are any illumination in the patent as to what that  the claim requires a controller adapted to regulate data flow between the mobile device and the data network requires data from a mobile device through a gateway to a packet based data network so it's it is establishing a connection from a mobile device through a gateway to a packet based data network and with that there are does that there's no question about prosecution history ok then what is regulating through the gateway meet what are you talking transmission between a mobile device through a gateway all the way to a packet base data network as well not just transmission that doesn't have to be any regulation there has to be some sort of regulation but it has to be through the whole channel your hon an example of regulation through the whole channel for example regulating access to the network would be regulating through the channel your honor that was something with pointed to in our brief the air the installed by individual users rather than rather than a cellular network operator and for that reason it's important that each base station has a unique identity and that's how the network can track where each ba as an add on base station in prior art each phone had a unique identity however the base station had no unique properties that the prior art systems had mobile devices with unique identities that were associated with subscribers the base stations themselves did not know what the board cited as the board says disclosing this limitation was exactly what the specification taught was disclosed in the prior subscriber is not a unique identifier of the base station and in fact loose it on the reference teaches that a single base station can have multiple sim card installed those are sim cards that are associated with an individual user not sim cards that are associated with the base station when you use an identifier for a base station that's associated with an individual rather than the base station that's no longer a unique identifier of the base station which is what the claims require that the unique identifier of the user that a mobile device could have its own unique identifier but a base station not this system is different because the because the base station itself must have a unique identif is different from the unique identifier of an individual user or i subscriber ok unless my colleagues have per their questions i think we're out of time will give you two minutes or a bottle any further question on behalf of unified patents unified agrees with the director's positions on review ability of the real party an interesting issue the determination is institution level under section three file and again drive and east of series to foreclose review of the issue but before the final written description final written decision that would affect the status of real party in interest and it's raised by the patent owner do you think the decision in the like to turn to the merits of patentability and firstly in regulating dataflow term and how that is met by ferris the short court should come to the same conclusion of the board regulating data flow between the mobile device and the packet based data network require nothing more than controlling the flow of data between those two endpoints and the claim language speaks for itself the claim of size a controller adapted to regulate data flow between the mobile device and the data network the claim does not recite the flows through the gateway it must be regulated through the gateway but it is not in dispute the data flows through a gateway what is at issue is where such data regulated between the two if you look at the prosecution history isn't there a suggestion there by the patent that it has to regulate through the gateway i don't believe that's the case your honor i believe that in the prosecution history of the the portion that the market is pointing are ambiguous on that point i believe that that the applicant was distinguishing the johnson reference based on the johnson references type of network meaning between a circuit switch and a pack switch network and the presence of a gateway at all in johnson not whether johnson regulated data flow through a gateway or that regulating data flow through a gateway is required  that is fair and i apologise for that you're out of it and i'm a bit of that confusion is is because the specification as the board pointed out does not use the word regulate so if we are looking at the intrinsic record and  what's in the patent we resort to the claim language and regulating between those two endpoints just means regulating anywhere on that path between the mobile device and the packet based data network and agree that there's no control or in the johnson the the johnson prior art the the applicant i'm sorry the examiner confirmed that in prosecution  that limitation and so the applicants statement that the johnson were not material as to whether their claim acquired through a gateway or not  again the question turns on want to claim language the claim or cite a gateway comprising a unique identity and nothing more is required of the unique identity the claims do not specify the nature of the unique identity a point which parking cannot contest without resorting to reading in additional limitations not present in the claims text based on the claim language the unique identity is not attributed to or limited to or associated with the gateway the board's finding that lucid arm discloses a unique let me start with the regulate dataflow term page five hundred and seventy eight of the appendix is the prosecution history and your honor discussed this with counsel when the patent owners describing johnson and the prior reference literally bowls regulating data flow that's exactly what the board is identified in this case they have identified the exact feature that was distinguished during prior art and the board not explained why it reached a contrary decision there's very briefly turn i'm sorry but where does the examiner say that exactly this is the this is the final office action response before the claims were allowed  you're hearing over the question think all counsel the case is submitted
