Introduction This section is not normative.
Print Article This is part 6 of a multi-part series exploring the history of software patents in America. In both Ergo and Noah, the outcome rested upon whether means-plus-function claims in a software patent were indefinite and, therefore, invalid.
In both cases the claims were lost. I strongly disagreed with the rulings write an algorithm for implementation of breadth first search Ergo, and while I would have come down differently on Noah Systems at least the Court in this case explained themselves. These cases are very important though because they give us the best glimpse yet into understanding the disclosure requirements for software patents that utilize means-plus-function claim language.
Understanding this particular aspect of patent drafting may be crucial moving forward given that some believe that means-plus-function claiming may be one way to get at least some patent claim coverage in the wake of Alice.
Therefore, given that the extraordinarily strict disclosure requirements mandated by employing means-plus-function claiming, this technique may well be the future for software patents.
Certainly adhering to the extreme disclosure requirements in the Algorithm cases will be a best practice moving forward even if you do not employ means-plus-function claiming, and it will likely remain a best practice until some statutory or common law relief from Alice is achieved.
The appeal in Noah arose out of an action brought by Noah against Intuit for infringement of the U. The system allows a business or individual to connect to the computers of companies with which that entity conducts business so that information regarding financial transactions can be transmitted between them.
The parties agreed that this is a means-plus-function limitation performed by a processor. Ultimately, the Federal Circuit would determine that the algorithm disclosed was incomplete.

This lead the Court to explain that when the specification discloses an algorithm that only accomplishes one of multiple identifiable functions performed by a means-plus-function limitation, the specification is treated as if it disclosed no algorithm. Indeed, an incomplete algorithm means no algorithm at all, which means that what one of ordinary skill in the art would understand from the disclosure is no longer relevant.
Representative independent claim 12 recites: A financial accounting system for a first entity such as an individual or a business, said system comprising: This determination lead to a decision rendering all of the asserted claims indefinite because they lacked the required corresponding structure.
Accordingly, the district court entered summary judgment of invalidity in favor of Intuit. Ultimately the Federal Circuit would find that the district court erred in determining that no algorithm was present, because at least a partial algorithm was present, but did not disturb the ruling because of the determination that a partial algorithm is as good as no algorithm at all for purpose of interpreting means-plus-function claims in a software patent.
On appeal, Noah raised two different, albeit closely related, arguments. Noah argued that the district court erred when it: The Federal Circuit pointed out that means-plus-function claiming involves a quid pro quo. In exchange for being able to draft a claim limitation in purely functional language, the applicant must describe in the patent specification some structure that performs the specified function.
Importantly, the functional claim language covers only the corresponding structure, material, or acts described in the specification and equivalents thereof, which confines the breadth of protection otherwise seemingly provided by purely functional claiming.
The Federal Circuit also acknowledged that it is undisputed that the question of whether a claim is indefinite is based on how the claim limitation would be understood by one of skill in the art. The Court went on to say, however, that the testimony of one of ordinary skill in the art cannot supplant the total absence of structure from the specification.
These two statements seem logically inconsistent, to put it politely. It is impossible for means-plus-function definiteness to be about what one of skill in the art would understand and then to simply refuse to ask what one of skill in the art would understand.
The Federal Circuit has set up a logical impossibility, which is why this must be treated as a special rule as applied to software patents that utilize means-plus-function claiming. If someone of skill in the art would appreciate something based on the disclosure then there has to be something there to lead that person to the appropriate understanding.
If there is nothing that would lead one of skill in the art to an understanding then it would be impossible to understand. Whether the Federal Circuit likes it or not, the reality is they are supplanting their own determination about what is disclosed in computer software patents for the understanding of one of skill in the art.
In This Chapter. In this chapter we will compare the data structures we have learned so far by the performance (execution speed) of the basic operations (addition, search, deletion, etc.). We will give specific tips in what situations what data structures to srmvision.com will explain how to choose between data structures like hash-tables, arrays, dynamic arrays and sets implemented by hash-tables or. These cases are very important though because they give us the best glimpse yet into understanding the disclosure requirements for software patents that utilize means-plus-function claim language. C++ programs for the implementation of Breadth First Search(BFS) for a given graph C++ programs to implement the Prim’s algorithm to generate a minimum cost .
If we were dealing with tangible embodiments the illogical nature of the syllogism would be obvious, but because we are dealing with intangibles like whether a disclosure teaches a claim even without an algorithm the lack of logic flourishes. There is clearly a significant and specific corollary to the traditional means plus function law when the claims relate to software.
In any event, the Federal Circuit explained that current case law regarding special purpose computer-implemented means-plus-functions claims is divided into two distinct groups: The distinction is important because if an algorithm is disclosed then it matters what one of skill in the art would understand.
If no algorithm is disclosed, or as a result of this case if a partial algorithm is disclosed, it is irrelevant whether one of skill in the art would understand the disclosure. In order to get to whether someone of skill in the art would understand the disclosure the Federal Circuit explained that there must be an algorithm present that addresses both aspects of this functional language.
Write a SymbolGraph client srmvision.com that uses depth-first instead of breadth-first search to find paths connecting two performers. Determine the amount of memory used by Graph to represent a graph with V vertices and E edges, using the memory-cost model of Section Breadth-first search. Breadth first search is one of the basic and essential searching algorithms on graphs.
As a result of how the algorithm works, the path found by breadth first search to any node is the shortest path to that node, i.e the path that contains . The following features are at-risk, and may be dropped during the CR period: application of grid placement to absolutely-positioned boxes “At-risk” is a W3C Process term-of-art, and does not necessarily imply that the feature is in danger of being dropped or delayed.
I think this is redundant information for breadth first search algorithm, because it strongly depends on goal - what you want to find out from search.
If you want to find just shortest route from A to D,- than OK, your suggestions is good. The difference between breadth-first search and depth-first search is order in which elements ar added to OPEN list..
In breadth-first search new nodes are appended to the end of OPEN list.
