select which account mode is desired at the appropriate point in time but a human user cannot be the subject that carries out the zones of the clients it's physically impossible for a human user to quote obtain  connection with the allow designed in this context must mean that the payment system is programmed to select the appropriate account for each transaction this is because it is possible to design the future actions of a human user and that limitation is not met when you have user selection to be clear i still don't understand your argument in a mess simming it's not waived and there's a strong waiver argument i got that the other side i'm sure is going to make but merchant or purchaser selectively but it doesn't say that the system controls the selection actually it does that has basically linguistically speaking who is  could have us you can have a system where where it can it can work as either the purchaser or the the merchant but still have the they the one who's doing it do the selection i mean i just i'm i'm trying i'm having a hard time understanding how that specification language actually says we're not going to have a system in which they use or can decide whether they're going to be the merchant or not so the important system a unified database everything being within the same package infrastructure and that can't be done if you're having a user separately creating accounts a user separately selecting which account am i going to be locked into which m really can only be the payment system why would linguistically speaking why would you have a list of actions and some of those actions were saying the payment system carries out some of the actions we're saying the use the input would be making selections about what to do about whether what to buy or sell an online marketplace but that's different than a slew of selecting the account rules and everything that goes along with it because there's a lot of other infrastructure that's carry through all that isn't different for the user to select an account role compared to making a decision whether to buy or sell an item it's fundamentally different and it's it's literally is because this construction for which think the future is now advocating was not raised in the underlying proceedings in computers council pointed to two different places in the underlying records where it claims to have argue had this type of selection process and what they wanted to do was to come up with a better system so that when i go searching for a product i automatically am treated as the purchaser birches versus when i'm responding to someone's search then i'm automatically treated as the seller so why isn't that it a novel development over the prior art and something that reasonably could a question well but i mean that but that's very different from a circumstance and with whether you agree with them or not but from a circumstance that where you're where you're not involving the user in the selection process involved in the process but you know say i'm you know say i am manufacturing something that i like to sell but i need to buy the ingredients you know sam baking something i need to buy the ingredients and i need to sell the end product and so the question is do do i have to make a selection as to which i am which role i'm playing or is that mere fact that that there is an order going out automatically change that role correct that's what specification does not define what constitutes the sign or person prescribe any particular method of assigning a role that's a different type of talking about the fact that the claim system so lacks the account rules that's one thing another thing is how during any particular transaction but the critical part is that this process of selecting the user account when that's appropriate has to be carried out automatically after it's user input elicits this process the rest and what that means and i believe that if it's lashes out the contours officially to understand within that the scope of the claims that you must have the payment account selecting these roles and specifically the one thing we know for certain i but not one that counts with the payment system being adapted to selectively choose these roles in response to user input and that's a fundamental difference the automation is what is fundamental it's what allows the all the elements of the claim to work in harmony and again allow a single database allowed single payment system everything within unified right instead of going to separate pages and having the user have to navigate choosing you know now me and my my
