Narrative Opinion Summary
In this patent infringement case, Akamai Technologies, Inc., and the Massachusetts Institute of Technology sought damages from Limelight Networks, Inc. for infringing their '703 patent relating to a content delivery network (CDN) system. After a jury awarded Akamai $45.5 million, Limelight challenged the verdict, citing defenses such as inequitable conduct, laches, equitable estoppel, and unclean hands. The court, led by District Judge Zobel, found that while undisclosed information was material, Limelight failed to prove intent to deceive the Patent and Trademark Office, negating its inequitable conduct claim. Limelight's defenses of laches and equitable estoppel were unsuccessful due to a lack of evidence supporting unreasonable delay or misleading conduct by Akamai. Furthermore, citing the Federal Circuit's clarification in Muniauction, the court ruled that Limelight did not exert sufficient control or direction over content providers to establish direct infringement, granting Limelight's motion for judgment as a matter of law. Consequently, the court declined to enforce the jury's verdict. This case underscores the complexities in proving joint infringement and the high bar for establishing inequitable conduct in patent litigation.

Application: Following the Federal Circuit's Muniauction decision, the court ruled that Limelight's interactions with content providers did not meet the control or direction standard necessary for direct infringement.
Reasoning: The Federal Circuit's decision in Muniauction raises the question of whether vicarious liability is essential for satisfying the control or direction standard.
Inequitable Conductsubscribe to see similar legal issues
Application: Limelight's claims of inequitable conduct against Akamai failed as the court found no intent to deceive the PTO, despite the materiality of the undisclosed information.

Application: Limelight's defenses of laches and equitable estoppel were not successful due to insufficient evidence of unreasonable delay by Akamai and lack of misleading conduct.
Reasoning: Limelight's defense of laches is unsuccessful. Regarding equitable estoppel, the key issue is whether Akamai intentionally misled Limelight about infringement prior to the lawsuit.

Reasoning: However, following a Federal Circuit clarification on joint infringement standards, the court granted Limelight's motion for judgment as a matter of law (JMOL) regarding the infringement issue.
Unclean Hands Doctrinesubscribe to see similar legal issues
Application: The court found no egregious conduct by Akamai to apply the unclean hands doctrine, as Limelight's assertions were linked to unsuccessful claims of inequitable conduct and equitable estoppel.
Reasoning: However, unclean hands is a remedy for only egregious conduct, and the evidence does not support claims of bad faith or unfair actions.
