of this court in schreiber foods is that transfer of all patents and causes of action moves an action unless cured prior to final judgment the court followed the supreme court's be vacated so the only substantial question is whether olympics can be substituted after remand in vacate or and have a judgment reinstated and all of plex relies on the supreme court's precedents under federal rule of civil procedure twenty one dollars which allows why is it that since the transfer took place after the injunction was answered that they can't be substituted under rule point well because the injunction has merged into the final judgment the action is moot and i think there's a number of precedence that if there's a pending injunction appealing the action becomes mo t that the appeal must be dismissed so olympics relies relies on the supreme court's precedents under federal rule of civil procedure twenty one dollars which allows adding or dropping parties in the interest of justice but as the nice circuit explains rule twenty one dollars can only be invoked to perfect jurisdiction over the original party's claims and to afford relief to does not hold that that's moot we have an argument in the subsequent appeal that discusses whether or not that you need to have standing in order to file a brief but as far as driver foods yes you're correct that if the transfer on the post trial motions were ruled on in december and the district court asked the parties to reconcile the verdict and its other orders and said that it would then later enter a final judgment and since final judgment is determined based on the district court's intent that it be the last act of the case and there are a number of matters to reconcile about there were concerns conflicting pre judgment interest awards  issue as well as conflicting parts of the opinion that one point i said any any in your view all of even though the only thing in front of us is an injunction which did predate the transfer of interest our focus should not be on that which would come within schrag or rather later developments in the district court leading to whatever the final judgment the relevant time period is is transferred before final judgement and to do any of the cases that you cited note the distinction between an appealable injunction and a final injunction pre frontal judgment transfer no they don't your honor but we would submit that the relevant consideration is movements of the action as a whole and so i think for those reasons we think that  district court to consider substitution at the district court level and then enter a new final judgment why is that in permissible and that's what i was mentioning with the bain case all of the precedents in which plex relies lanie and newman green and so forth all involve federal rule of civil procedure twenty one dollars which allows adding or dropping parties in the interest of justice and appellate adding a drop in the party but the only reason that the court do that and they say it's sparing is that rule twenty one allows you to perfect your stiction over the original parties claims to afford relief to the original party so turning to the concentration claim term that does not permit the district court's construction it concentration is not any ratio of weights but the ratio of a part to a hole that's  concentration of active agent quote in the mixture necessarily refers to the active agent that is part of the mixture all the intrinsic evidence particularly specification column sixteen in the prosecution history confirms the text  the language of that claim they in the next year language was actually not entirely clear and also thought that the specification u error deference to have a standard to the magistrates reliance on the express testimony of the plaintiff's expert that a person of skill in the art would understand the usage in the art in the field of the mixture language as referring to the weight of what you put into it not the weight of the thing that remains after the chemicals do it is just a function of the ph and you can see the fractional composition chart at appendix twenty four thousand and ninety nine dollars so i think it's understood that all of within the range of it all ins and that supports our construction because if one hundred gram mixture or something like that but that's not what it says and your honor i just wanted to touch quickly on the summary will give you some more time ok so the are there any more questions are  only the claim method steps in for this reason our expert of pines is a prototype testing which all the plex relies failed to prove infringement the testing calculates breakage after three applications as well as additional unclaimed conditioning steps multiple bond building treatments will reduce breakage more than one treatment and the report itself also said that any treatment that reduces snags  can help in substantially lowering the number of broken fibers so any additional unclaimed conditioning steps would destroy the results plex could of the did not commission industry standard testing replicate only the steps of the claim method and assess breakage after one application the expert testimony on the inadequacy of the prototype testing creates a jury question as to infringement why is that not present here what travel century says that it's actually the control and benefit test is the alternative to the st actor performing all steps of the infringement  so what you would have to show is that the nd actor was under their direction or role of the st actor and that's the court's decisions and eli lilly and  my and travel century all say that if you have it's not enough to have just product instructions but you have to actually deny the benefit any benefit doctor's instructions limelight you wouldn't have access to the to the computer service unless you follow the instructions and then travel center you wouldn't have the benefit of the security screening unless you followed the exact instructions it shouldn't even be a game an issue of fact is to control but at a minimum there can't be summary judgment the next thing i'd like to point out is a summary judgment has to be vacated as the indirect infringement and the reason get summary judgment against the stylus just by proving product instructions because there's no necessary infringement of infringing use inference of infringing use and thus l'oreal indirect infringement is also unproven and that applies across the board in all claims so all the plex did not prove a single instance of indirect infringement but if it had the most that would justify partial summary judgment the district court plenary grant a summary judgment on all indirect infringement claims completely skewed the jury trial and this is important because unlike reasonable royalty this court's precedent golden blunt and other cases say not enough to prove a single instance of direct infringement to get lost profits you have to prove each infringing act that you claim resulted in a lost sale and what this than an issue that relates to the injunction it's not your honor and the reason is what that might be true if it were a reasonable royalty case like lucent because a reasonable royalty you are just have to prove a single act the royalty is determined at the date of st and frenchmen and loose and says well if you don't prove any other infringement you might not get much of a royalty but this court has been clear you know if you're trying to get lost profits and they claim lost profits from every single sale so the court has said you have to prove that there is an infringing act that resulted in each particular lost sale which means you have to prove it has to be induced because this is in direct infringement  message so you have to prove that and that it's possible they could have done that by proof by having a depending on what the evidence they put in but it would have to be a survey of l'oreal customers during the period based on  what percentage of the stylus used it for lightning versus coloring and how and what was the breakdown of that stylus usage and ready for and i write in understanding that am i right in understanding that my my point is whatever the break down would be they can't get plenary summary judgment on the entirety of their claims because inferences can inferences are drawn on each cause of action which is separate use so at least a summary judgment  there's no necessary inference that everybody used it for bleaching and bleaching in compliance with the method so they really had a failure of proof all they did is really prove the possibility that one could use l'oreal's products to infringe but when a product is not necessarily infringing their burden is to prove a specific instance of infringement with a single act or perform the method step and they just didn't bother to do that i would note they did try after their s judgment motion they put in with their opposition brief for the st time a declaration of one stylist that we point out that's defective because there's no she didn't testify as to when she used it that has to do with whether if the district court's claim construction about the molecular weight in the range in in the mixture is right then nevertheless there was at least question is this did you say that would change the numbers but it would change the numbers in you did you ever say it would change the numbers in a way that would affect coming into or going out of the it's not a question of the molecular weights as much as it is in terms of the concentration and this is a little bit complicated so let me just take a moment to our point is that on concentration all the plexus proof did not match the district court don't mean is that right and then and if that's right how could that possibly change the only conclusion that matters which is at the figures that the plaintiff's expert came up with stay with in  dr freeman pointed out so here's the key the active agent formulation here are the step one products so for the purposes of claim construction what is germane is the raw material added into was added into the activities in formulation the step one bottle curiously dr boris attempted to calculate with n m r results the freema layer in the step one bottles themselves and he treated that as a proxy for what was added and that's wrong because dr freeman demonstrated that the m r i results as you mention do not distinguish free acids from mally and that if you actually calculate the free acid amounts in the step one bottles the concentration then the question of how much difference that makes in terms of the concentration turns on the molecular weight difference doesn't it and that's trivial no your honor because it's it's not true and there's no testimony that it's not that it just has to come from some form of the lake acid it has to come from the free acid in the raw material solution and that's what's never calculated and that's what the charted twenty four dollars ninety nine cents which show that you're highly acidic solution like that is only going to have a fractional part of free acid that's just their construction now they run from their construction page thirty two dollars of the brief say we should just treat it as you know at some point maybe at the vendor it is vendors plant it came from pure black acid there's no testimony to that effect but that's what you look to somewhere down the line approach where he relied on the step one bottle that you know that doesn't work and i would also try now to also say well what about the safety permanent injunction appeal was the one that was noted i believe by judge trump to which is that undisputably the transfer of interest here occurred after the permanent injunction and after the notice of appeal was filed loriot cited no case law for the proposition that somehow subsequent events were guarding a final money judgment could affect standing to appeal the permanent injunction or to make the case entirely moot given the lack of case law i think it's it's worth just putting this in some practical terms because really  deciding that issue which is not decided by schreiber in any sense on a clean slate and this is a hyper technical argument that l'oreal's making that would lead to needless waste in terms of a remand to the district court to sort out whether to join or substitute all the plex and ok but but your assumption there is that that the remedy and they say what what case says that if there's an error in entering a final when  that proposition so the st the st case i would point to which is also cited in the briefs is the molina case in the u s supreme court and i respectfully disagree with my friends on the other side on that question because in what lanny when this case got to the s supreme court there was a question of whether the party had standing at all and what the supreme court said is in order to avoid having to deal with that issue we're just going to add for the st time in the u s supreme court we're going to add a party that ind diversity problem and diversity we do believe is relevant here because among other reasons the shriver case relied on caterpillar which is a diversity case so in fan you had a real and and what was ultimately held by the th circuit is all you had to do was solve the diversity problem and then reinstate the original judgment you didn't need to go through entirely new trial now we think even that step would be needlessly wasteful because we've already had a me and then what happened they they dismissed the non diverse party that's right so that in the original trial there had been a trial a verdict there was a diversity problem it went up on to the u s supreme court went back down and what happened was the what actually went back down to the district court and the question was once we solve the disk diversity problem do we just reinstate the old original judgment without further ado or do we have to conduct an new trial and the th circuit said you reinstate the original judgment you don't go through an entirely new trial but i don't want to lose sight of the fact that that issue if it's relevant at all relevant to the money judgment not to the permanent injunction now there is another issue on this score that i'd like to address which is even if there is some sort of merger problem created by the final judgment i didn't hear my adversary on the other side talk about when finality occurred with regard to the money judgment and we've explained in our brief that there was finality as of december th team and keep in mind that the transfer occurred in january two thousand and twenty so let me explain a little bit why there was fine now yes of december th that is when the district court decided the post verdict fact l'oreal filed a notice of appeal because it was concerned that there might that might be construed as final and yes it labeled its notice a protective notice but there's nothing in the federal rules that talks about protective notices it's something that parties occasionally do but at a minimum it suggests that l'oreal itself recognized that there might be finality as of december and it wanted to get its notice on file and not take that risk our position here is yes there was finality as of december seven b when a party files a notice of appeal it waived the separate judgment paper requirement and therefore the separate judgment paper that was entered ultimately in march two thousand and twenty was unnecessary and did not remove finality that was present as of december  excuse me excuse me your honor i should correct what i said this issue in the context of this appeal was framed up in the motion papers on substitution and jointer we did make that argument in our in our motion papers in that case we also have made that argument when you make the other case no in this case the in the reply in support of our motion to join our substitute which was filed after l'oreal made its jurisdiction standing argument for the st time we did make this finality point about december twenty one team we have also we and l'oreal have both briefs this issue and the money judgment appeal which we attached to a recent opposition to orioles motion for leave clowe a supplemental brief for the court covered well it covered the injunction had already been entered the permit injunction are administered but what the december th twenty one team order did was it resolved all pending issues in the case that related to not just the injunction but the money damages issues by that as well as pre judgment interest and in fact when the parties ended up submitting their proposed separate judgment papers there was no disagreement in terms except for some linguistic issues about the how the counterclaim should be described there really was no difference in terms as to whether schreiber is correct in light of our disposition is unnecessary to address this argument about whether rule twenty five c of the federal rules of civil procedure allows for substitution for the st time on appeal we respectfully submit that that is dick to this court and it's unpublished decision in total containment which granted it's unpublished but held that there could be substitution for the st time an appeal in that circumstance the th and th circuits in the slate and cases have similarly so held and therefore that's the better view also because whatever one thinks of maligning there is an issue about whether we want to go through a meaningless exercise of a real man for further proceedings that in the district court when it's really discretion however i think it's worth pointing out that will twenty five c does not impose a time limit similarly in cases among others of the you know low case in this court and the th circuit's decision and t o c say that substitution is entirely permissive which again suggests that there's no strict timeline and in any event there was no long delay here the transfer occurred in january two thousand and twenty and all of flex explained that it would seek substitution in about march of tw there was no lengthy delay here such that would justify a denial of such a motion so that's that's our position on that question unless there are any further questions i'm standing i'd like to turn to the claim construction issue and  i'd like to start with you know when we look at the claim and we think that when you look at the words in the mixture those don't say when you don't say when you weigh them away gases they just they just don't it could be construed either way and so what this court has done in prior cases this judge toronto pointed out is to look at it from the standpoint of the skilled artisan and in that context we have not just the magistrate judge in the district court but also the let me try to answer the question a different way though it is true that the for one path and i think it's important to clarify talks about my legs acid or salt lake i said that and i think what i write what the parties agree on i believe is that once you combine the active agent formulation with the bleaching formulation there will be no non ionic malays acid left it will all have been neutralized so at most you will have some salts and in the four hundred and nineteen patent context the problem with that had prevailed on claim construction we did not attempt to print friends with purposes to point to salt because we thought all we needed to do was point to malenka acid as it existed before being added but let me just briefly move past that question because i think it's correct well i think we're still on claim construction and i'm not entirely sure when that piece had expert what was filed but i still would submit that it's relevant evidence of what a skilled artisan but let's look to and in want to just correct briefly what i said that six i'm not no i'm not saying that at all your honor in the district court's claim construction decision it refers back to the p tab it relies on the p tab for the persuasive authority so that you were just referring to i believe it is but i'm not one hundred percent in all candor i'm not one hundred percent sure of that but there are various if not there are other similar statements but the p temp did rely on this is not an outlier the n that's the active agent if i could move on to the summary judgment issues the let me start with the question of the m r and i think it's very important that before when you and gets to n m are to recognize that there's an alternative way to finding that there cent of thirty five six percent seven percent which is eleven seven percent which puts the number in fact over ten seven as opposed to under which that no reasonable juror could find that it was something like zero in fact it was somewhere between ten dollars to eleven dollars which is within the range once you use the instructions that are provided in more eos documents about how to combine it with bleaching formulation and so boris relied not just on and m r casting but also on those documents now judge toronto we green with your point about the relative molecular weights what we're talking about st of all the claim construction starts with the pure molay acid before it even enters a solution and yes dr heard mr caird say but not quite in a way i could follow something to the effect that some of them out of the eight found in the bible in the ultimate mixture  might not have come from the lake acid that was in the acquis a solution there might be other predecessors of mally at that did i understand that right and can you eliminate that i am not sure if he was making that assertion or not but i don't know where else would have come from and i am not the chemist or the experts here but dr borsch explained using the on the molecular weight point or not she key was he was relying on yes because no nuclear magnetic resonance imaging is by its nature a weighing of all worry about finding scientific fact peel i understand i understand that concern but i think again i would go back to the document that is a tireless separate approach than and i'm are here which acid did it say i summa did say that would make a difference in the numbers did it ever say that would make a big enough difference in the numbers that it would alter the only conclusion that mattered which was that the accused products were within the claimed range i don't believe they took that further step nor could nor could they have given the negligible w me turn to the step three attribution point briefly and i have two just two quick points on that before you head get to that can you address this business about there are two points about the the that are made by l'oreal about the bleaching formulation which applies to both of the which is l'oreal's marketing of its active agent products for use with l'oreal's own bleach products and we know from the record and i just gave those the sites that l'oreal's on bleach products include as their very st ingredient the no they don't require it but again if we if we look at what l'oreal actually did with the products in its own live demonstrations it said when we do these demonstrations we ourselves are using our is the matrix call to make all three lines of products l'oreal itself and this goes again i haven't got to it yet but direct result induced infringement we don't even need to get to induced infringement to support from an injunction here because we have indisputable evidence from l'oreal's own witnesses marino morris and sure robbie that there demonstrators are out in the field doing these steps every day using their own active agents and their own leeches and we know from the labels that their own bleaches include purcel fate at the very st ingredient interim orders bars promotion or use of the staff one step twenty three dollars and three dollars greens and then infringing manner so when they're doing these demonstrations they are both using as well as promoting the use but if this court wants with my opponent on the other side one instance is and we have many more than one instance but one instance is enough for a permanent injunction the extents under lucent is a question for damages not a question for the permanent injunction and  we have done enough and l'oreal's arguments in the main ignore its own dock but can it can i can i just ask this i mean why wouldn't the extent the relevant to at least the weighing of harms that would be required for the injunction and standard that is if if the injunction prohibited l'oreal from doing a very wide range of saying is only  know that in some very narrow subclass those activities would actually infringe and doesn't the balance of equity shift rather a lot i don't believe so and i think we have to keep in mind also the factor that l'oreal based on the summary judgment as an infringer based on the jury verdict is a willful infringer we also have to keep in mind that this is the entirety of all the plexus business whereas it's  a very minor part of l'oreal's business l'oreal is one of the biggest t v cosmetics companies in the world and in terms of irreparable harm we have shown enough not just from l'oreal's own actions but from l plus the instructions which yes they mention coloring but they start before they mention color and they talk about lightning and when you put all of that together maybe the extent of how many letters has are out there is an open question we think that that was decided by the jury and we'll get to that in the next case but we have enough for an injunction it shouldn't be allowed for an educated in french or to be promoting the infringing use of these products even to a single person and so i'm not  what you're saying is even if even a loreal is right about induced infringement years thing the injunction can be sustained because of these small number of alleged  direct investment by l'oreal well respectfully it's not just alleged it's testimony from their own witnesses that they did actually use these products with their own bleaches but beyond yes i would say that that evidence alone would support the injunction because that is a use and a promotion of the use which is what the injunctions proscribes of and infringe infringing process ok well whether they're let's suppose hypothetically that we don't accept that why isn't there a jury question on induced infringement i think that there may be a jury question on the extent of into used infringement that was decided by the jury what i'm suggesting to the court is that that is not necessary to sustain the permanent injunction here given the industry of the evidence we have of infringement whether direct or indirect and i do think that the there structed that that liability had been established including liability for induced infringement but i believe that they were but what the jury was instructed or found i guess and i respectfully submit is not necessary to sustain the permanent injunction here because of because of among other things the direct evidence as well as the lar declaration there was the argument by counsel but larry declaration is completely incredible but that is not a basis to deny summary judgment simply because a party asserts that something is incredible in terms of the date of the declaration it was signed on april  in terms of accepting a late disclose witness in those circumstances the final point i want to make even if this court has concerns about step three products and we don't think that the court should have concerns the step three products by their nature are called step three they necessarily refer back in their instructions refer back to steps one and two so the step three whether or not it itself fringes is again promoting and infringing use of step twelve and for that reason among others the injunction and can be sustained and should be sustained us to step three can i see unless i do have one further question i think can you say something about this after my aspect where at least the the allegations that involve the customer's use seem to require that a stylist and a customer be equated for direct infringement purposes and why why was the evidence sufficient for summary judgment in your favor on that question sure thanks to trounce of the the st preliminary point i would make is that laris in her declaration testified that she herself did all three steps including step three so we do have an example where we don't need to attribute a customer to a and the reason is because travel sentry doesn't impose some strict requirement that will cut off access to the process by the st actor if the nd actor doesn't do exactly what he was he or she was instructed to do it's more lenient and what it does is it focuses on the benefits so if there are instructions from the st actor to the nd actor and if there are benefits that are reasonably obtained by performing those instructions that is not under travel centric and under travel century who is it that is required to benefit is that they hear the home is there or is it a stylist it would be the home user and in travel century similarly by analogy it was the t s a transportation safety agency that was the actual performer of the steps and man and actually in your summary judgment papers did you address all of this  this whole akamai attribution question for the direct infringement that's that's relevant here i think it's actually to the induced infringement point but right well but it's relit whether it's relevant indirectly because without direct infringement there's no interest in transmission that's right you need direct inference and by some end user and you need some end user or attribute id and user to a performer all the steps and i believe this was briefed i'd be supreme court added the party specifically saying it was doing so so it didn't have to decide whether the pre added party had standing which means that what he did must be authorized even on the assumption that the original party lacked standing no your honor i think that this falls in the law as the as the skies are considered dangerous where you're perfecting the jurisdiction by adding a party but there's an article three controversy so if the court did not decide that the union lacked associational standing on behalf of the daughters that it might just but it but did it say we don't have to decide that so that what we are doing is a valid thing to do even if even if that union association did not have standing it must've been saying that right if it wasn't what it said is that you know perfect the appeal so but but it's different when the it's clear that the current parties have no standing case is moot so you have to substitute this isn't and not addition i would also point out and they urge the court to look memorandum the court's memorandum on the duplicative damages and the jury verdict and so that and then he says i will then enter a judgment this is not a matter of just this separate paper requirement and  it's true the parties agreed on the pre judgment interest starting with the latest of the jury verdicts but the point is the court hadn't held that the court was reserving to itself through to review what the parties came up with and the parties mr hand before they run out of time here could you address the question of whether the injunction can be supported on the direct infringement theory that we've heard from mr weisberg and i know it's the way i hear him he seems close to admitting that there might be genuine issues of material fact with respect to inducement but he says nonetheless there are instances here direct three and there's no allegation of proof of any direct step three and i would point out they cannot say laris st of all unless there is no evidence they point to that we her use of step three in the salon are the only input any evidence of inducement at all if they're relying on the instructions those are only for at home use there is no evidence of inducement but i would also push back on the idea that in one instance a direct infringement indirect infringement may just across the board if they had sued ten different stylists they couldn't prove summary judgement on all ten just based on this less so they that's part and only the breakage claims survive what should happen in this case the breakage claims are critical to the summary judgment if you uphold everything else the breakage alone would not prevent an injunction but you would have to uphold the step three issue and indirect for all those claims which includes the breakage claims and you would have to uphold the independent claims as well i would just point out one from the same flaws the issue is that you have to do what you use the molecular weights for is to determine the fractional composition of that weight that is free acid that's what dr freeman says and says hey you can't step one process and show that the free acid there under their own construction would be within the concentration ranges thank you i think unless my colleagues have further questions we're out of time thank you thank you i think
