procedural issue and one is a substantive issue the st procedural issue was the time bar and the time bar was triggered because i tried on which was a time barred party was a real party in interest before the i p r is were instituted and that's because before institution it was a clear beneficiary that had a preexisting and established relationship with the petitioner and the in this for days after institution our facts are different because the merger was announced publicly ten days after institution and they closed the merger during the i p r proceeding so what we had before institution was the had approached petitioner to acquire it before the petitions were even filed and then after the petitions were filed they negotiated an agreement to acquire petitioner they completed the due diligence during which they presumably learned about the litigation where these patents were asserted and the i p r is and then they made the offer to acquire petitioner and i try on the time our party said it was prepared to close the deal but then there was a delay of a few weeks during which the board instituted i p r proceedings and then they publicly announced ten days later that i was acquiring petitioner so in that sequence of events obviously there's quite a large sort of threshold question of whether this was all waived because you did not presented to the board why is this not a good situation for finding waiver  aspects that are not so the issue that we have here is whether the time argument as we've all city of arlington did not address that issue there was concern with a different issue which  whether an agency is interpretation of its own jurisdiction should be given chevron deference and we don't we don't have any chevron deference issues here because the board never considered the time bar and never interpreted it in the subpoena there's only one case that i'm aware of in the circuit where this issue of wave ability of a jurisdictional bar by the board has come up and that's this court's decision in g t annex and in that case they did not institution looked at some papers and realized that there was probably a problem here and then roughly speaking called in the parties and said to the patent go in there we invite a request for reconsideration of our institution decision correct and so the the allegation or the argument and she t n x was that the civil action bar had been raised untimely and but what the statute requires is that when the i p r is instituted you know and it's institution decision you must consider the time bar so the only requirement is to consider it an institution but of course often the board revisits their institution institution and were actively attempting to purchase the petitioner the only parties that were aware of this were petitioner and i tried and it was not publicly announced until ten  days after institution so you know in this case there is very good grounds to for the board to have considered it even after institution because you know he was aware of many of the fifteen the t work there wasn't just a negotiation for a merger korean situation i chime had made the offer that was later accepted ten days later to acquire them and said we're ready to close th so the deal was all done except they had to sign the paperwork and do it so they had a deal so and that was all done three and what do you think you bring that up to the attention of the agency i do not know why it was not brought up below merger was in the works and actually had an affirmative obligation to inform the board through its mandatory disclosures was the petitioner and they never disclosed it they never even disclosed it later after the merger was done and the stay we have we have no an announcement all you have is a letter from one company to another one that's just something like let's meet next wednesday have one and discuss potential  think it depends on the facts and circumstances but in but in this case we have a new much more happened they had gone through the process they completed due diligence they had a deal the deal was on the table and that was the same deal that was accepted after institution and there was a gap there so you know the deal was done like i try and had an interest they were that they were a clear beneficiary and they had a relationship because they were plotting to a and seventeen and twenty all require a means plus function limitation of wide area network for means or which which is referred to as one means in the claim and it's undisputed this is a means the board didn't do this and stead in the final written decision they played the philip standard and never identified the corresponding structure and the only corresponding structure explicitly linked to that function in the specification was that there is such a thing talked in the prayer well they made no finding that there was a conventional one radio in the prior art and petitioner concedes it never even identified conventional one radios in the prior art below to the board and we have two different ip artists here there's the i p r with the mayo and roach pyaar ground but it sure is not even disputing on appeal the that that priority includes a conventional one radio so that certainly should be reversed and on the other which is the other jerusalem again there was no finding was never identified so there is no factual finding that could support the th compatibility finding i'm into my r allegations that petitioner and silver spring at the time now i tried network solutions inc concealed the merger is contradicted by the additional materials that eighty i submitted into the record on appeal which shows that eighty i counsel was apprised of the merger it knew about the merger and in fact i am asked otter i tried network solutions inc argued to the district court that as a result of the merger it became a license d in the fourteen a disclosures which we cited too but it wasn't as if i try on ink and silver spring at the time had a preexisting relationship like we see in the cisco case or that it had already been acquired and the merger had closed prior to institution as we saw in the power integrations case in fact silver spring and i trying to think at the time we're competitors and if we were to adopt a position think one is that the sort of size of the litigation that would like to think that a company would be likely to rely on and timing their merger is not likely to be a frequent occurrence and moreover deciding the case on stacked the negotiations aren't the type that would give rise to a real party in interest we're not saying and our argument isn't that you have to have a closed merger for a party to become a real party in interest of becoming or be in pretty with another part it's the circumstances of the totality of the factual arguments in the r p i determination under applications and time and given the facts of this case there just isn't any evidence of  a real party in interest being created at any point prior to at the earliest january th twenty teen when the merger actually closed as i mentioned at the time in the interim between the dislike mergers have to close in order  upon not necessarily so there can be a letter of intent to do it it depends on the circumstances in the relationship so it's hard to answer the hypothetical without the complete set of facts but here and the specific facts of this case and one that's particularly important is the relationship between the parties during these negotiations they're represented by separate counsel they set up clean room procedures and i can direct your honour's to  and ninety seven which is one of the new materials introduced on appeal where the parties had to clean room procedures such that if the merger didn't close it wouldn't put either company competitive disadvantage and so that's highlights that these are not companies that were informally cozy with one another prior to the merger prior to the letter of intent or the agreement in plan a merger which was executed and signed on september th these were competitors which if the agreement did not close at the merger did not close on january th twenty teens then in fact i try to include a interest in silver spring not prevailing in the  under the facts of this case the closing d of the merger is important given the lack of any aligned interest prior to the closing of the merger you address the the marriage yes on the win means argument as was alluded to earlier the focus in briefing below was on the notion of the winnings having to communicate over a public network focus i think is probably the wireless remote metering unit the w r m u is a conventional land radio and that the board didn't make any factual findings about that and that's because in the proceedings below of helen's didn't make any distinction over the prior art based on that all the argument with respect to our grio just below and why it purportedly did not render this claim element obvious was that it didn't communicate over a public land and so there wasn't an of all the claims in the one thousand and sixty appeal dealing with the nelson or i'm sorry i'm getting confused dealing with the roach grounds in our opposition brief or in the we also pointed out that even if the court were to be inclined to adopt the new construction proposed by h e i on appeal that the evidence still supports  correspond to our expert dr solomon's opinions talking about the w r and you described in our preorders talking about how it uses c d m a communication communicating over existing cell phone infrastructure or cell towers and this corresponds to the conventional c d m a type way and radio described in the patent at appendix two hundred and seven column five lines five to fifteen this also aligns with a g i description of what a conventional land radio is which is a bit unclear from the briefing but one thing we know is that from appendix five hundred and fifty eight their radios that communicate over cell towers existing cellular infrastructure that's exactly affirm and as warranted i will say that i don't think you should get to the point of adopting a t i s can construction on appeal even if you move past waiver because i think if you read the board's decision it's clear that they did in fact adopt our proposed construction as a means plus function term where they said the function is transmitted and the structure is transmitted it is a structure that derives its name from the french in that it performs but there's then it rejected patent owners argument that it was limited to a public land or that the only type of structure that could satisfy the way and means limitation was a conventional land radio it's certainly one type of structure that can do it but the specification itself refers to it when meetings such as a conventional land radio elsewhere the function of transmitting is aligned with a conventional transmitter and as a result the board was just saying we're rejecting patent owners argument it's not limited to a public plan it's not limited to a conventional land radio the peach have didn't suggest that it was departing from its construction in the institution decision after eighty i didn't challenge the initial construction put forth by silver spring the petitioner it didn't suggest that it was not considering the term as means plus function and it didn't suggest that there was anything different about the construction that it applied previously in granting institution unless your honour's have further questions and we thank you for your voice thousand and seventeen entry that is where i try and made the offer that was accepted of sixteen dollars twenty five cents per share for i try on and that was done a few weeks before institution and if you are sorry what was the and we don't actually know what the relationship was we're just learning things from their f c c filings and from what they told the district court so this case should go back for the board to take a full analysis and get all of the facts about exactly what the relationship we have enough information just from petitioner's admissions and that's briefing these facts are not disputed that there appears to be a time bar problem in this case to go back to the board to determine whether it's time for and counsel also argue that it had no interest and and having the petitioner actually succeed and they because they were already licensed once they had made that offer and indicated they wanted to close the deal of course they had an interest in seeing succeed because that would impact the value of the company that they were trying to by turning to the claim construction argument that argument was not waive that council acknowledged they were aware of that argument it was presented in our pat means finding should be affirmed on these new grounds and these new arguments that they're making for the st time on appeal this court cannot do that under the administrative procedures act because judicial review is confined to the four corners  you did not really present to the board specific factual contentions that the radio or argue on this was unconventional apart from it didn't work o and they never identified a conventional radio in our journey to us and the only excerpt that the board reliant on to show a pattern ability is this one section in column three of our drew this that has no disclosure of hardware so i mean there's just
