court knows it reviews claim construction de novo the primary issue before this court is the construction of the term database that appeared in all of the pat below now we believe the intrinsic evidence is clear that the only only reason winter potations of the term database is a relational database figure one be also discloses that same relational database search fields are a foundational component for a relational database fields make a record stored in a table those are the key components of a relational database it's right there in the specification there's a number of terms in the claims here friends action id record index all classic hallmarks of a relational database there's simply no dispute on this patent or on these patents excuse me that this is a relational database based upon the unambiguous intrinsic record now  not two different kinds of databases most important that's in the background of the invention it's not in the for detailed description and it's referring actually just to how to access data from the web that's all it's talking about and it discusses a preferred method of doing that the common gateway interface but that's it is definitely not talking about the database that is the relational database described in the detail description also site to the ability that's referred to in the specifications as searching by categories however if you turn back to the previous page of the patent there's a description of all the fields categories is one of them so categories is a feel within a record clearly connote ing a relational database the fact that there is a tree structure within it that search will feel does not indicate whatsoever that this is not a relational database that's how they're set up the last argument that was made was with respect to a claims filing claim six of the three six seven patent that doesn't support a construction for anything other than a related relational database either claim five refers to the network server or interfacing with the database through c g i scripts and claim six refers to an s q l database those are simply preferred  ms for the relational database they are not an intent to claim a relational database only it is just dead clear from this intrinsic record that a relational database is the proper construction it is true that these claims don't use the word relational but of course that isn't the question these claims are read by a person of ordinary skill in the art it cannot be disputed that a person ordinary skill based connecting ok well let's make sure that in order to get where you want to we have to understand database not simply to permissibly include relational database fact when that was disputed the m b big actually had a file system just like you would have on windows it did not have a hierarchical database the only evidence in the record about a hierarchical database was in mis film and speculation that was a hierarchical database that was designed by i b m and abandoned it was not used by anybody of ordinary skill after the late sixties so our view is that number one clear below there's no dispute about that that if it's limited to a relational database it excludes the files that's correct but if it includes a relational database and could include the file system or any yes i think that yes and i'm just trying to understand your argument i think that's a fair assessment we have arguments that even if the n b b or even if the definition is much broader is the court adopted below that the n b b still does not invalidate all these claims but certainly they're a step closer than they would be if the court adopted our claim construction for a relational database but that you have to have the construction excludes a reasonable interpretation that's the that's the core issue that was in the lower court yes exactly the whole foundation for this opinion your honor was the issue of finding that a database could include a file system that's what led to strike that is the entire basis for this decision that is the basis for the scope and content of the prior art it's the basis for the differences between the prior art in the pan did invention and it's the affirmed by this court with respect to the construction that was adopted for database by the lower court then there's a different question that needs to be asked for purposes of obviousness for certain cl well your honor that was not an issue that was raised by anybody below or on appeal and my view is that there is certainly enough structure in all these claims with a database of the other elements follow up on these questions about anticipation obviousness let's just assume for a second well let's do it this way there was no evidence in the court below none by anybody that it would would have been obvious to modify the n b b with a relational database and arrive at the claimed invention that just was not evidence that was below think what a person ordinary skill would encounter is that they would look at the way that that device operated and understand that it would need a complete redesign in order to make it work with a relational database and eventually they would start from scratch s with the court's permission we'd like to reserve three minutes for my co counsel christopher cal representing craigslist this may please the court from judge players questions and judge newman's question it's clear you understand the issue it is whether in fact the common term used in the computer field database should be larded up with definitions and limitations that appear nowhere in the specification and goes beyond importing the preferred body meant graph ons construction is database means solely a relational database managed by a database management system software running on but separately from an operating system in addition to that their expert puts forward one thousand additional limitations many of which are nowhere discussed in the specification and says this little term database means all these twenty twenty elements graph on the pads are clear about what the invention disclosed in the claimed invention in those patents the focus of those patterns is about publish  internet our content on the internet and which users have complete control over the content and classification of their entry they are not directed to databases they're not directed to database specific technology the pro facing is that obviously long before its applications were filed in december one thousand nine hundred five professor mcbride had launched a very system of a very similar system that reads all over these claims indeed he presented a paper at the first worldwide web conference in early one nine hundred ninety four in which he described how his system allows users to post content and exercise complete control over the database entries grania vance's this argument about plai construction despite the fact that in earlier litigation its own expert can gave a completely different construction for the term database directing your honor's attention to join appendix nine in the previous litigation was asked for his definition outside the context of the patterns of the term database he merely opined it is an organized collection of information he was further asked there's a database need a database management system of sort answer no a database doesn't need a database management system again they base management system appears nowhere in the claims it's mentioned briefly in the preferred body image but that's imported into graphics construction similarly adjoin appendix page two zero zero two two zero zero four graph on sex work in the previous litigation was asked about his definition of database in the context of these patents and he said it's an organized collection of information it is both a data store in a data source very similar to the construction that was adopted by the district court in this case interestingly enough there's no mention of the term relational anywhere in the pass none there's no discussion anywhere takes a common term database large it up with all these limitations but this court's precedents are clear in order to overcome that database should be given its plain and ordinary meaning a collection of information that can be stored in access they need to show that inventors demonstrate an intent to deviate from the ordinary in a custom meaning of a plain term by including in the specification express manifested expressions of manifest exclusion or restriction represent clear disavowal claim sco is always prepare for given last night if i came across an interesting decision from this court admittedly it's a nonpresidential decision from earlier this year but it is the movi decision moving vs real estate alliance from march twenty second two thousand and eleven and in that case this record was faced with construe in the very same term obviously different paths but the term database in a district court case came up with this construction and i'm reading from page five of the court's opinion creating the structure that houses data additional language but then such  including the tables the fields in each table and with relational data databases the relationships between the fields in the tables on appeal this court held that the district court construction was improper element update and in each one of those cases apparently there was no this you could about the construction of and then the trial judge either held the obvious or anticipated  we don't understand that the only issue that terms of whether the database is limited to relational databases as far as the ultimate outcome of this case putting aside that other mother goble to moore to operate it so in essence they are just going to struction issues on image professor mcbrien as part of our motion for summary judgment submitted a declaration saying that even in fact if you accept that the district court's construction  it would have been a trivial modification to grab an image and it's stored as part of the multiple bold voyage graf a never contested that so to the extent that there's any issue about image and claim destruction issue that issue's been waived the evidence was a everybody neutral charging for accessing web entries already existed at that point so the entry on his question this is a claim destruction issue and it is principally resolved on the construction of database those database exclude every kind of other behalf of craigslist i want to present the alternative arguments that even if the court finds that the district court misconstrue the term database and that that term should properly be construed to be a relational database considered by the district court set forth in the king pharmaceuticals case the argument has to have been adequately raised below first and second supported by the record with respect to the argument being raised below craigslist brief this argument fully in our reply brief in support of the summary judgment motion it was briefed in reply simply because the evidence that it's based on which is principally that the expert declaration submitted by gra argument the judge was presented with this argument and heard oral argument from both sides on this issue of obviousness based on the combination of the n b b and a relational database so as to the record supporting the of the it was it's well established in the graph on its own expert testimony that relational databases were common in the mid ninety's and in fact she testified that relational databases were common in the in the early eighty's when she began working in the field and in particular ms spielman testified and this is a record in her declaration that was submitted by grandfather  day fifteen fifty eight three sixty and paragraph forty three and forty eight for declaration and j a fifteen fifty five paragraph thirty six of her death for ration in addition she testified about the the relation of use of relational databases in the indictee ninety's at j twenty one twenty three through twenty five which is her deposition testimony but the one piece of evidence in the record that i want to highlight for this court database over and above the file system like what was used in the n b b and in particular paragraph forty three of her declaration she says a relational database overcomes many of the obstacles imposed on applications using a file system or a hierarchical database to store ablation of databases or to store relational data as relational databases are designed specifically to manage and organize large amounts of related data so use of my time is up and based on her  simply no evidence of that in the record that the record shows that there are an expert of stuff of the five that everyone knew how to use relational databases and there's nothing to suggest that it would be difficult to combine the b b with a relation i'm going to take mr coward to task on that last comment because it's my whole point there was no evidence below with respect to combining the n b b with a relational database that's their burden or they didn't lay it down we know from the objective record that that code for the n b b was written for a file system and we know that there is no chance that it could employ the relational e well i think i think it's all the graham factors i think it's the scope and content of the prior art improper factual findings i think it's the level of ordinary scummy are there was no explicit finding there was an opinions were based upon a file system being a relational database or being a database within the scope of the climes ok thank you very much
