Infringement Litigation: Themes $ $ $ Theme 1:
5
Theme 1: $$$ “High stakes” litigation: damages “Microsoft ordered to pay $512 million to Alcatel-Lucent…” (June 2008) “Medtronic ordered to pay $400 million to Dr. Michelson…” (October 2004)
6
Theme 1: $$$ “High stakes” litigation: injunctions “Court considers Blackberry injunction… Case settles for $612 million…” (March 2006) “DISH Network DVR may be enjoined…” (August 2006, still pending)
7
Theme 1: $$$ High cost of litigation Amount at Issue Cost Through Trial Less than $1 million $750,000 $1-25 million $3 million More than $25 million $5.5 million Source: AIPLA Economic Survey 2007

Theme 2: Complexity Complex technology

Theme 2: Complexity Complex technology 1.A method of encoding a sound signal, comprising the steps of: providing a codebook circuit for forming a codebook including a set of codevectors Ak each defining a plurality of different positions p and comprising N non-zero-amplitude pulses each assignable to predetermined valid positions p of the codevector; providing a device for conducting in said codebook a depth-first search involving a tree structure defining a number M of ordered levels, each level m being associated with a predetermined number Nm of non-zero- amplitude pulses, N > 1, wherein the sum of said predetermined numbers associated with all said M levels is equal to the number N of the non-zero-amplitude pulses comprised in said codevectors, each level m of the tree structure being further associated with a path building operation, with a given pulse-order rule and with a given selection criterion; wherein: in a level 1 of the tree structure, the associated path-building operation comprises the following substeps: choosing a number N1 of said N non-zero-amplitude pulses in relation to the associated pulse-order rule; selecting at least one of the valid positions p of said N1 non-zero-amplitude pulses in relation to the associated selection criterion to define at least one level-1 candidate path; in a level m of the tree structure, the associated path-building operation defines recursively a level-m candidate path by extending a level-(m-1) candidate path through the following substeps: choosing Nm of said non-zero-amplitude pulses not previously chosen in the course of building said level-(m-1) path in relation to the associated pulse-order rule; selecting at least one of the valid positions p of said Nm non- zero-amplitude pulses in relation to the associated selection criterion to form at least one level-m candidate path; and wherein a level-M candidate path originated at a level-1 and extended during the path-building operations associated with subsequent levels of the tree structure determines the respective positions p of the N non-zero- amplitude pulses of a codevector and thereby defines a candidate codevector Ak.

Theme 2: Complexity Complex legal issues Complex business issues
13
Patent Litigation: Themes Theme 3:Uncertainty
14
Theme 3: Uncertainty Complexity Uncertainty Appeal reversal rate over 30%
15
Theme 3: Uncertainty Changing law “Supreme Court reverses Federal Circuit again…” “Proposed patent reform legislation…”
16
Patent Infringement Litigation Issues in Dispute
17
Patent owner’s claims: Infringement Direct or Indirect
18
Issues in Dispute Patent owner’s claims (cont.): Remedy Damages Injunction
19
Issues in Dispute Accused Infringer’s defenses: Non-infringement Focus on patent claim elements
20
Issues in Dispute Accused Infringer’s defenses (cont.): Invalidity Novelty (§ 102) First to invent? On-sale bar
21
Issues in Dispute Accused Infringer’s defenses (cont.): Invalidity (cont.) Obviousness (§ 103) Was the invention obvious at the time? KSR case (2007)
22
Issues in Dispute Accused Infringer’s defenses (cont.): Invalidity Defects in the patent document (§ 112)
23
Issues in Dispute Accused Infringer’s defenses (cont.): Equitable defenses Inequitable conduct Laches, estoppel
24
Issues in Dispute Claim construction (“Markman”) Scope of claims is critical to infringement and validity
25
Patent Infringement Litigation Procedure
26
Pre-filing activity Contact between the parties? Who sues? Patent owner or accused party Whom to sue?
27
Procedure Pre-filing activity (cont.) Where to sue? Federal court “Rocket docket” vs. local Int’l Trade Comm’n (ITC)
28
Procedure Pre-filing activity (cont.) Diligence and preparation
29
Procedure Pre-discovery period Lawsuit filed but little $$ spent yet Legal strategy Business strategy
30
Procedure Discovery period Discovery tools and sources Documents Witness depositions Written discovery
31
Procedure Discovery period (cont.) Discovery strategy Cost/benefit Disputes
32
Procedure Discovery period (cont.) Expert discovery “Battle of the experts” part 1
33
Procedure Claim construction Prepare early and often Markman proceedings and order
34
Procedure Dispositive motions When? What issues?
35
Procedure Trial
36
Procedure Trial Story / themes Evidence “Battle of the experts” part 2
37
Procedure Appeal What issues? Reversal statistics
38
