reference to the interaction between the bit holder and the big block only ok the project seven says it would be desirable to provide a more efficient means for allowing removal of a bit from a bit holder and there are similar references that reference the interaction between the bit and the fit holder as a removable one explain to me how you could get to say what you say  feature under cuts that would be underneath the flange of the danger of the bit where it connects with the bit holder as undercuts be facilitating extraction of the bit that's actually not a feature of any of the claims in five six seven or one five five either of the few because they focused so much on the bit in terms of the claims construction process they want to cite that this is so the fact that this is really a didn't hold their patents and not a bit patent that's what's novel about both of the patents and suits it's a bit patent is about bit holder this isn't about bit this invention is a bit holder and i guess what you've just acknowledged with me i think is that the inventors invention is a bit holder and one of his preferred embodiments may in fact be directed to a bit but that isn't what's claimed and i guess the country addiction is the notion that this patent is only about a bit holder that's what i'm trying to point out to you is that that this patent seems to me to disclose and suggest it is easily removed because all you do is apply heat and if the brace melts away and the only thing that's holding this on there is that but i might also add that ease of remove the billet is not a condition of this either and is not one of the claims it's not referenced in any of the claims if need be the term removable really isn't the only the term mountable here's the bit the multiple in some fashion to the front part of the bit holder but remove ability is not addressed at all and that's i think another this assembly off of what they call the steel body but we would say is virtually identical to the the bit holders that is the noble component of psalms but that the patent does say specifically says it provides in five six seven patents in law so it really truly is a straight reference in the specifications that is disconnected with the claims and that's the only place where it appears interprets the term bit in the claims construction process it terminates that the bit has to have a shank we don't see that a good sound basis certainly in the intrinsic evidence that we it does ok in connection with the bid holder the claims expressly reference and shank which goes into a second for in the  through said that block right it's these two components here but not the bit i don't understand is your argument that that a bit doesn't have to have a shank at the plain meaning that it wouldn't include a shank or that the shank doesn't  basically it could be this could be this it could be something entirely different from out of those or any number of them out there it's not specific to the past nor is it important to the past how the bit gets affixed to the bit hold or you can choose not to have a bit older and you can have it if it's directly to the block without a bit older and if you want to be certain if you want to be absolutely certain that you don't have a bit older so me provides an example from the prior art other than that it's it's what was shown here so as a competitor of so mieses you can't rely on that statement that there's no been told or shown here then what can you rely on however that doesn't jive with what they've said and what's shown in this prior reference i don't feel that can job now in order to make that argument they pretty much have to say that the bid is anything but it doesn't really have structure that it's braised on there is a bit they want to remove any real limitations to if they want to say that it is just anything can be can be that bet well i think they're saying it has to be a cutting tool a fixed to the bit holder and that's i guess what i understand them right but where does that come from and it's certainly going to come from a description specification in the specification those have talks about how the bits such as how the rotat plain meaning definition comes from the specification no the plain meaning comes from one of ordinary skill and they are reading the specifications are you telling you the plain meaning of one of skill in the art when asked in this particular industry the mining industry what is a bit they are going to say it has to be mounted in a big holder it has to be removable it has no of course not that doesn't make sense right if you walk up to one of skill in the art and say what is the bit they're going to say it's the sharp cutting and on the end of these mining tool right so i'm not saying the claim doesn't require the bit to be mountable i'm saying the word bit in another itself doesn't necessarily require mt ability does it otherwise why would the claim require mountable if it automatically meant that two sixty two is a record that's all that references about it says undercuts and none of the claims of either one five five or five six seven address the undercuts because th erred on the clean air then applying the claims even as they interpreted the claims to the no the pick device by concluding even if you assume for the sake of argument and we certainly don't agree with it that the that the bit had to have a shank  it does have a shape there is a locally cylindrical aspect to this right there it does mounted inside the bid or steal body as they call it of fact because it is the district court described this whole test of whether it's from the bable or not it said well it has the determination has to rest on whether it was intended to be removed by  devices this is simple and reassemble using usable components again which most would be the part and the stinger on the top so it's clear that they contemplate through their method patent that this would be removable and the components of this device again all of which the user can the mining company which is using this or whomever if they're using your product can make swap that out themselves or they have
