is even a single in body mental lacking pivoting to say that everybody agrees that non titting motion can be substituted at some level how does that tend to degree angle you're still tilted a little bit as well if you're out of zero degree angle you're not tilted at all and that's and that's and that's one of our points with environment thirteen and in volume and thirteen the angle of it's called alpha one  ex is presented as a variable variable that can take on a range value now in the figure is shown as a non zero angle but there's no reason for the specification but just to be clear you are asking now for a claim construction that would include a zero angle we're asking for a contract yes we are judging and we're asking for a claim construction that would include specification especially the object statements of the objects of the invention which characterize the objects in a manner that is generic to both getting coupling members and coupling members that move in a straight  met one of the things that talks about is the engage position what it calls the rotational force transmitting position where the two with a couple members on the printer driveshaft are coupled together and what this tells us is says and what it shows and then essentially the problems why why act ilmi movement doesn't work on a body of thirteen and so i know the course discussed a little bit already but i just want to make sure that the language is before the court you know if you look at th position to the rotational force transmitting angular position so that says when it's engaged it pivots and the pictures eighty figures eighty seven dollars eighty eight cents show that but then it also discusses and then there's this middle paragraph which  nineteen which we haven't talked about quite so much yet this is on appendix to twenty nine columns seventy eight around line forty actually thirty eight dollars it says each coupling described embodiment thirteen and in the figure it shows why you need to have the pivoting specifically to disengage the coupling number and so if you look at it by figure eighty seven for example which is on page thirty seven drum mechanism that has the coupling member on the end of it which in our brief is a yellow but coupling member has kind of the thing in the middle and then you have a connecting to the driveshaft which is coming from the other direction and so figure eighty eight showed us how that got in talking about when they're lined up actually but you need to get them into place and you need to get them out of place and what i mean by that is you need to insert the printer cartridge to engage it and then you need to take it out to disengage it and the point i was trying to make is that to take it out to disengagement engage it as well as putting it in you need to have the axial movements and this figure eighty seven in particular shows that because the spring is pushing forward there's just no mechanism to move it only devices well that's that's actually the next point i wanted to make your honor which is that it's a fundamentally different design and different mechanical structure if you have a device that doesn't pivot and moves on actively and if you look for example at how our devices work this is on page eight of our brief it shows a picture and it requires really a whole different mechanical configuration and page we show that our coupling mechanism which is the blue lever and the green lever that when the printer door is shut the green lever pushes in and then it causes the coupling member to push outward and so this may be too much detail but i guess the point i'm trying to make i really it's a it's a whole different design and a whole different mechanic to say that there's actually only movement and that design just isn't present in the specification it's not present in the words it's not present in the figures it's just not there i think you as i don't know that there's a common specification because this is the continuation application and the point that was being made by the expert in that case was the essence of the invention and specifically the language it's the claims that define me in invention and if so and if they're looking at a different claim that it is not a leap well the claims are always read in light of the specification and the report dr was the icing on the cake you know everything's pointing in one direction here and so if you only look at the words and figures in the specifications i think you know based on everything that the l g a focused on that that itself would present a sufficient package for the nineteen and this is an appendix to twenty nine at around line thirty nine of columns seventy eight and i do acknowledge that this says each coupling member described above has the following structure but then when you look at the coupling members less even more fundamentally this is a discussion of embodied this is not a discussion of the invention as a whole this discussion of inviting it nineteen comes about five columns before the president  vention statement as one of the things that we think the l a j did wrong in her analysis was to this discussion of environment nineteen with the invention as a whole this present invention sentence in the sentence at the end of the specification that stands alone this term the president mention is used much much more often and the summary of the invention portion the specification for example and every time it's used it's used in the context of a statement that is generic to both pivoting and pivot in couple of members it's used to describe objects of the invention that are generic to the both types of mood and so we're talking here about a very very isolated sentence and a sentence that's simply not strong enough to trigger a finding of disavow  the answer is a clear yes the result would have been different all about that sentence and so then we need to think about the propriety of that result it's one sentence that's written as an observation not a mandate it says that doesn't say the president vention
