Roman,5,Staking Your Claim,October 9, 2018, Michael J. Roman,6,Staking Your Claim,October 9, 2018, Michael J. Roman,7,Staking Your Cl

3、aim,Anticipating your competition can be difficult.,October 9, 2018, Michael J. Roman,8,Claiming Your Stake,How do you patentably define an invention?View the invention at a level of abstraction consistent with invention over the existing state of the art.Identify and name all of the elements needed

4、 to make the invention work. Keep these elements to a minimum.,October 9, 2018, Michael J. Roman,9,Claiming Your Stake,Describe (“limit”) each of the identified elements. Limitations necessarily inherent in an element need not be explicitly introduced. For example, a square necessarily has 4 equal s

5、ides.Describe the relationships between the elements.,October 9, 2018, Michael J. Roman,10,Claiming Your Stake,Describe the function of each element.Describe the end result produced by the co-operation between the elements.,October 9, 2018, Michael J. Roman,11,Refresh,US Patent 1,183,492 Issued 16 M

6、ay 1916 Title: Weapon Inventor: A.B. Pratt,October 9, 2018, Michael J. Roman,12,Claiming Your Stake: An Example,Imagine that you have just invented the worlds first 4-sided box.How will you protect this brilliant invention?,October 9, 2018, Michael J. Roman,13,Levels of Abstraction,A vessel for hold

7、ing things. A box having a base and 4 walls. A wooden box having a base and 4 grooved and mitred walls.,October 9, 2018, Michael J. Roman,14,Naming the Elements,A base. A number of walls. Is 4 the right number of walls? Means for joining the walls to the base, unless such joining is inherent in the

8、structure of the base or the walls.,October 9, 2018, Michael J. Roman,15,Limiting the Elements,Explicit Limitations Physical characteristics shape flexibility temperature Chemical characteristics substance state Implicit Limitations A square has 4 sides,October 9, 2018, Michael J. Roman,16,Limiting

9、the Base,A base A planar base A planar base with 4 edges A rectangular base A square base A rigid square base A rigid square prismical base A rigid wooden square prismical base,October 9, 2018, Michael J. Roman,17,Limiting Each Wall,A wall. A 4-sided prism. A trapezoidal prism. A bilaterally symmetr

10、ical trapezoidal prism.,October 9, 2018, Michael J. Roman,18,Limiting The Joining Means Explicit Structural Limitation,An angle bracket having a first arm and a second arm that define between them a 90 degree angle, the first arm adapted to engage the first wall, and the second arm adapted to engage

11、 the base, such that the angle bracket is operable to retain the base and the first wall in abutting perpendicular disposition.,October 9, 2018, Michael J. Roman,19,Limiting The Joining Means Explicit Means Limitation,Means for joining the first wall to the first edge of the base, such that the firs

12、t wall and the base are retained in perpendicular disposition. “Means” is interpreted according to the invention description in the patent.,October 9, 2018, Michael J. Roman,20,Limiting The Joining Means Implicit in the Wall Limitation,A bilaterally symmetrical trapezoidally prismical wall defining

13、an elongated channel breaching the prisms minor parallel face, the channel being adapted to receive and retain a portion of the first edge of the base and to thereby retain the base in perpendicular disposition to the prisms minor parallel face.,October 9, 2018, Michael J. Roman,21,Relationships (Ba

14、sic Concepts),Relationships help to indicate that you have invented a patentable combination, not an unpatentable aggregation. Relationships make claims easier to understand. Concrete, structural relationships are less vulnerable to attack or misinterpretation. Relationships should be completely def

15、ined with reference to the claimed elements; claims should be freestanding.,October 9, 2018, Michael J. Roman,22,Relationships (Box Example),Means for joining the first wall to the base, such that the first wall and the base are abuttingly and perpendicularly disposed. A bilaterally symmetrical trap

16、ezoidally prismical wall, defining an elongated channel breaching the prisms minor parallel face, the channel being adapted to receive and retain a portion of the first edge of the base, and to thereby retain the base in perpendicular disposition to the prisms minor parallel face.,October 9, 2018, M

17、ichael J. Roman,23,Function (Basic Concepts),Function makes your claims easier to understand. Function must be supported by the structure you ascribe to the elements and relationships. You cant claim results. Your claim will fail if you vaguely describe element or relationship structure, relying on

18、function in place of structure. State the purpose of the invention or an element. Explain the inventions or an elements structure.,October 9, 2018, Michael J. Roman,24,Function (Box Example),A vessel for enclosing objects, comprising: a substantially planar base; four prismical walls; and means for

19、joining each wall to an edge of the base, such that each wall is perpendicularly disposed to the base and the four walls together form a perimeter circumscribing the base, whereby the four walls and the base define an enclosure.,October 9, 2018, Michael J. Roman,25,Refresh,US Patent 2,626,151 Issued

20、 1953 Title: Golf Practice Apparatus Inventor: Unknown,October 9, 2018, Michael J. Roman,26,Validity,A patent claim is valid if:it defines something that is new and inventive compared to the current body of knowledge,but without describing any embodiment of the current body of knowledge.,October 9,

21、2018, Michael J. Roman,27,Infringement,A product infringes a patent claim if the product includes all of the elements set forth in the claim.If a product includes all but one of the claimed elements, it will not infringe the claim.If a product includes all of the claimed elements plus additional inv

22、entive or non-inventive elements, the product will still infringe the claim.,October 9, 2018, Michael J. Roman,28,Validity v. Infringement,Validity What precisely have we invented?,Infringement What aspects of our invention do we want to prevent others from using without our permission? What aspects

23、 of our invention are strategic for our company? What aspects of our invention will the marketplace deem valuable.,Patenting is a waste of time and money unless you haveclear answers to the following two business questions:,October 9, 2018, Michael J. Roman,29,Validity v. Infringement,A broad claim:

24、 is more likely to capture competing products as infringements, but is also more likely to be ruled invalid as capturing existing technology within its scope.,A narrow claim: is less likely to capture competing products as infringements, but is also less likely to be ruled invalid as capturing exist

25、ing technology within it scope.,October 9, 2018, Michael J. Roman,30,Validity v. Infringement,October 9, 2018, Michael J. Roman,31,Validity v. Infringement: Claim v. Current Knowledge,October 9, 2018, Michael J. Roman,32,Validity v. Infringement Claim v. Actual Invention,October 9, 2018, Michael J.

26、Roman,33,Validity v. Infringement Claim v. Competitors Product,October 9, 2018, Michael J. Roman,34,Validity v. Infringement,October 9, 2018, Michael J. Roman,35,Refresh,US Patent 257,103 Issued 1882 Title: Motor Inventor: J. Sutcliff,October 9, 2018, Michael J. Roman,36,A Workshop Problem,Assume th

27、at the state of the art is the 4-sided box.Would the following products infringe a patent claim for the 4-sided box?Would the following inventions support valid patent claims in view of the 4-sided box?,October 9, 2018, Michael J. Roman,37,The Claim,A vessel for enclosing objects, comprising: a subs

28、tantially planar base, four prismical walls, and means for joining each wall to an edge of the base, such that each wall is perpendicularly disposed to the base, and the four walls and the base define an enclosure.,October 9, 2018, Michael J. Roman,38,The 3-sided Box,Facts to consider: The 3-sided b

29、ox uses less material than the 4-sided box. The 3-sided box is smaller than the 4-sided box. Triangles are the most stable shape; their structure resists deformation.,October 9, 2018, Michael J. Roman,39,The 6-sided Box,Facts to consider: Artists consider the 6-sided box more attractive than the 4-s

30、ided box. Your companys trademark is a hexagon. Honeycombs are the most efficient subdivision of area.,October 9, 2018, Michael J. Roman,40,The Claim,A vessel for enclosing objects, comprising: a substantially planar base, four prismical walls, and means for joining each wall to an edge of the base,

31、 such that each wall is perpendicularly disposed to the base, and the four walls and the base define an enclosure.,October 9, 2018, Michael J. Roman,41,The 1-sided Box,A claim to a 1-sided box would give you wonderfully broad protection, extending to boxes with an arbitrary number of sides; however,

32、 because a 1-sided box doesnt seem to work, it cant support a patent claim.,October 9, 2018, Michael J. Roman,42,The 1-sided Box?,How many sides does this box have? Are sides the best way to describe this box or do we need to shift abstraction levels?,October 9, 2018, Michael J. Roman,43,Patent Stra

33、tegies,Include a range of broad and narrow claims, some favouring infringement, some favouring validity.Claim the invention as your competitors will sell it, not as your customers will use it. For example, dont claim batteries or extension cords.,October 9, 2018, Michael J. Roman,44,Patent Strategie

34、s,Claim the invention to maximize the royalty base. For example, include expensive elements in some of the claims.,October 9, 2018, Michael J. Roman,45,Patent Strategies,File families of patents instead of stretching one patent too thin. A family of narrow patents can work like a wall or a minefield

35、, keeping competitors out of your market. You can litigate one patent in the family without putting the rest of the patents at risk of invalidity. You can more easily subdivide licensees.,October 9, 2018, Michael J. Roman,46,Refresh,US Patent 35,600 Issued 1862 Title: Combined Plow & Gun Inventor: U

36、nknown,October 9, 2018, Michael J. Roman,47,A Case Study,Draft Beer Beer connoisseurs appreciate the head found on a draft beer. The head is created by the draft serving equipment. A pressurized dispensing line drives gas through the beer to force it from the keg, thereby liberating some of the gas

37、suspended in the beer. Neither a can nor a bottle dispense beer with the same quality of head.,October 9, 2018, Michael J. Roman,48,The Guinness Insert,A chamber 17 at the bottom of a beer bottle 1 has a tiny orifice 18 through which beer 19 and gas may pass between the chamber 17 and the beer bottl

38、e 1. When the bottle 1 is sealed, the beer 19 pressurizes the bottle 1 to a pressure above atmospheric. The chamber 17 fills with beer 16 until the chamber 17 headspace 21 balances the bottle 1 headspace 20. When the bottle 1 is opened, the headspace 20 disappears, and the pressure differential caus

39、es beer 16 and gas to be expelled from the chamber 17, which encourages the surrounding beer 19 in the bottle 1 to release suspended gas.,October 9, 2018, Michael J. Roman,49,The Guinness Claim,A beverage package, comprising:a sealed container having a primary chamber containing beverage having gas

40、in solution therewith and forming a primary headspace comprising gas at a pressure greater than atmospheric; .continued on next slide,October 9, 2018, Michael J. Roman,50,The Guinness Claim (Continued),an insert located in the primary chamber and having a secondary chamber with a volume less than th

41、at of the primary chamber and a restricted orifice through which the second chamber communicates with the beverage in the primary chamber, said secondary chamber comprising gas at a pressure greater than atmospheric so that the pressure within the primary and secondary chambers are substantially at

42、equilibrium, continued on next slide,October 9, 2018, Michael J. Roman,51,The Guinness Claim (Continued),said package being openable to open the primary headspace to atmospheric pressure and the secondary chamber being arranged so that on said opening the pressure differential caused by the decrease

43、 in pressure at the primary headspace causes at least one of the beverage or gas (preferably beverage) in the secondary chamber to be ejected by way of the restricted orifice into the beverage of the primary chamber and said ejection causes gas in the solution to be evolved and form, or assist in th

44、e formation of, a head of froth on the beverage; and continued on next slide,October 9, 2018, Michael J. Roman,52,The Guinness Claim (Continued),means to retain said insert at a predetermined location in the primary chamber of the container.,October 9, 2018, Michael J. Roman,53,The Problem,The new i

45、nsert works well with regular beer but works too well with lighter beer. Beer and gas expelled from the chamber at the bottom of the container liberate gas from the surrounding light beer. This liberation cases a chain reaction, and so much gas is liberated that a flat beer with a great head is disp

46、ensed.,October 9, 2018, Michael J. Roman,54,The Task,Improve the packaging for use with light beer.,October 9, 2018, Michael J. Roman,55,Solution 1,The downward facing orifice in the chamber 10 is replaced by a tube 15 that extends upwardly through the can 1, such that the gas and beer 5A expelled f

47、rom the chamber 10 interact with only the top portion of beer 20 in the can 1.,October 9, 2018, Michael J. Roman,56,Claim for Solution 1,A beverage package, comprising:a sealed container having a primary chamber containing beverage having gas in solution therewith and forming a primary headspace com

48、prising gas at a pressure greater than atmospheric; .continued on next slide,October 9, 2018, Michael J. Roman,57,Claim for Solution 1 (Continued),a secondary chamber containing gas at a pressure greater than atmospheric and having a seating which receives one end of a tube extending within the prim

49、ary chamber so that the secondary end of the tube opens into the primary chamber at a position remote from the bottom of the primary chamber and said one end of the tube communicates or is to communicate with the secondary chamber for the secondary chamber to communicate with the primary chamber by

50、way of the tube, . continued on next slide,October 9, 2018, Michael J. Roman,58,Claim for Solution 1 (Continued),and wherein said package is openable to open the primary headspace to atmospheric pressure and said opening creates a pressure differential causing gas and/or beverage in the secondary chamber and tube to be ejected by way of the tube into the primary chamber to cause evolution of gas from solution in the beverage for developing froth in the primary headspace.,
