This case involves Pozen Inc. suing Par Pharmaceutical Inc., Alphapharm Pty Ltd., and Dr. Reddy’s Laboratories Inc. for patent infringement under the Hatch-Waxman Act, seeking to block FDA approval of generic versions of Treximet, a migraine treatment tablet combining sumatriptan and naproxen. After a bench trial, the court issued detailed findings of fact and conclusions of law on the patented therapy's development, which uses simultaneous dosing to address both initial migraine symptoms and relapse by targeting distinct biological mechanisms. The court concluded that the defendants' proposed products infringe the asserted claims of the '499 and '458 patents because they contain the same drug combination in a single tablet, meet the timing and duration requirements, and are marketed for migraine treatment. The reasoning relies on evidence that the invention was unconventional compared to prior art focused on sumatriptan monotherapy, with the combination providing synergistic longer-lasting efficacy as shown by clinical data and expert testimony.

The case was a patent infringement suit brought by Mirror Worlds against Apple, alleging that features in Mac OS X (Spotlight, Cover Flow, and Time Machine) and certain mobile devices infringed three related patents on document stream operating systems that organize, display, and archive data chronologically. After a jury trial, the district court ruled on multiple post-trial motions, granting in part Apple's renewed motion for judgment as a matter of law while denying Mirror Worlds' requests for enhanced damages, royalties, fees, and other relief. The court found insufficient evidence to support infringement, either literally or under the doctrine of equivalents, because the accused products did not satisfy key claim limitations such as displaying a cursor or pointer sliding over a stack of documents without a click, and it struck additional evidence not presented at trial.

This case involved an ERISA plan fiduciary, ACS Recovery Services, seeking to recover approximately $50,000 in medical benefits paid to defendant Larry Griffin from a tort settlement he received, by imposing a constructive trust or similar equitable relief under ERISA Section 502(a)(3) against Griffin, his special needs trust, and related parties. The district court adopted the magistrate judge's report and recommendation, denying the plaintiffs' motion for summary judgment (including a default judgment request against one defendant) and granting the defendants' motion for summary judgment. The core reasoning followed the Supreme Court's decision in Great-West Life & Annuity Ins. Co. v. Knudson, holding that the relief sought was not truly equitable because the settlement proceeds were not in the defendants' possession but had been placed in a special needs trust and used for other purposes, making the claim essentially one for legal restitution under a contractual reimbursement provision.

In this patent infringement case, Clear With Computers sued multiple defendants and settled with all but one, producing the settlement agreements but resisting discovery of related negotiation communications. Defendants moved to compel production of those communications to evaluate the agreements' admissibility and reliability for proving reasonable royalty damages, while CWC sought a protective order. The court granted the motions to compel and denied the protective order, holding that the communications were relevant to assess whether the settlements accurately reflected the patents' value amid noted inconsistencies in amounts paid and the absence of non-litigation licenses. The decision emphasized a case-by-case approach to admissibility, the increased relevance here due to the nature of CWC's licensing business, and that non-settlement privileges would still apply.

In this patent infringement lawsuit, Southwire alleged that defendants Cerro Wire and Encore Wire infringed U.S. Patent No. 7,557,301, a continuation of an earlier patent also assigned to Southwire. The defendants moved to stay the litigation pending ex parte reexamination of the '301 patent by the PTO, citing recent developments including the PTO's initial rejection of all claims and Southwire's subsequent amendments to the independent claims. The court granted the stay, finding that the amendments neutralized potential prejudice to Southwire from ongoing alleged infringement by competitors, that the reexaminations would likely simplify the issues for trial, and that the case remained at an early stage prior to claim construction, expert reports, or summary judgment motions. The court balanced these factors against Southwire's arguments of business harm and concluded that a six-month stay was appropriate.

This case involved ClearValue suing SNF entities for infringement of U.S. Patent No. 6,120,690, which describes a water clarification process using high molecular weight DADMAC or Epi-DMA polymers combined with aluminum chlorohydrate, along with claims that SNF misappropriated three related trade secrets concerning polymer blends, manufacturing methods, and pH adjustments. Following a jury verdict finding patent infringement and misappropriation of Trade Secret #1 with associated damages, the court ruled on post-trial motions including defendants' request for judgment as a matter of law and a new trial, plaintiffs' motion for final judgment, and a request to vacate prior sanctions. The court granted JMOL and a new trial to SNF solely on the Trade Secret #1 misappropriation claim but denied relief on all other grounds, upheld the patent against an inequitable conduct challenge based on lack of clear and convincing evidence of intent to deceive the USPTO, partially granted entry of final judgment, and left the sanctions award intact due to ClearValue's earlier discovery violations.

This case involves a patent infringement dispute in which Mirror Worlds, LLC accused Apple Inc. of infringing multiple patents related to document stream operating systems, time-ordered information displays, and methods for organizing files in computer systems, while Apple counterclaimed infringement of its own patent on similar information organization techniques. The court construed disputed claim terms across five patents by examining the claims, specifications, and prosecution history under Federal Circuit precedents such as Phillips v. AWH Corp., giving terms their ordinary meaning to a person skilled in the art. It also addressed Apple's motion for partial summary judgment of invalidity due to indefiniteness under 35 U.S.C. § 112 ¶ 2, granting the motion in part and denying it in part based on whether the claims provided sufficient definiteness. The opinion reproduces representative claims and applies principles that claim terms must be read consistently and in context with the specification.

In this patent infringement case, ReedHycalog sued Diamond Innovations for allegedly infringing patents on partially-leached polycrystalline diamond elements, seeking damages based on a reasonable royalty. The court addressed Diamond Innovations' motion in limine to exclude evidence of fourteen prior licenses to the patents-in-suit, five of which arose from litigation settlements. The court denied the motion, ruling that all fourteen licenses are admissible under the first Georgia-Pacific factor for calculating a reasonable royalty because they involve the same patents and royalty structures. To address concerns about prejudice, the licenses may not be identified as resulting from litigation. The court found that the probative value of this evidence outweighs risks of unfair prejudice or jury confusion under Federal Rule of Evidence 403.

Donald E. Smith sued the United States under the Federal Tort Claims Act for negligence and premises liability after falling from a scissor lift at the Lone Oak, Texas Post Office while training as an employee of an independent mail transportation contractor. After a bench trial, the court found for the United States and held that Smith take nothing on both claims. The court reasoned that Smith was an invitee but failed to show a dangerous condition on the premises, as the scissor lift was equipped with safety cords, buzzers, and warning stickers; Smith was aware of the need to use the safety cord yet did not do so; and the USPS exercised only administrative oversight over the independent contractor, which was responsible for training its own employees and ensuring safe use of the equipment.

In United States v. Greer, the defendant pled guilty to possession with intent to distribute crack cocaine and faced a guidelines sentencing range of 70-87 months calculated under the 100-to-1 crack-to-powder ratio. The court granted the defendant's motion for a variance from the advisory guidelines, adopted a 1-to-1 ratio for determining the base offense level, calculated an alternative range of 21-27 months, and imposed a sentence of 24 months imprisonment plus three years of supervised release. The ruling relied on Supreme Court authority in Kimbrough v. United States and Spears v. United States permitting district courts to reject the 100-to-1 ratio, followed by consideration of the 18 U.S.C. § 3553(a) factors on a case-by-case basis after computing both the standard and alternative guideline ranges. The court determined that no further variance from the 1-to-1 range was warranted given the defendant's criminal history category and lack of violent offenses or weapons involvement, and announced it would apply the 1-to-1 ratio in future crack cocaine sentencings.

This case involves the construction of claims in U.S. Patent No. 6,218,930, which covers methods and apparatus for delivering power over Ethernet to devices designed to accept it safely. Network-1 accused Cisco and other defendants of infringing certain claims of the patent. The court provided constructions for various terms such as "data node," "access device," and "secondary power source," and determined that the term "control means" is indefinite while other terms are not.

The case involved defendant Kerry Scott Baker, who pled guilty to three counts of producing child pornography involving his own minor children. After sentencing him to 360 months in prison, the court bifurcated the restitution issue, appointed an attorney ad litem for the three minor victims, and held a hearing to determine appropriate restitution amounts. The court ordered Baker to pay each victim $150,900 for past and future treatment and counseling costs plus a share of the ad litem's fees, for a total of $462,000. The awards rested on statutory provisions including 18 U.S.C. § 2255(a)'s mandatory minimum damages of $150,000 per victim, expert evidence of long-term health and mental health costs, and Supreme Court precedent recognizing the enduring harms of child pornography production and distribution.

In United States v. Paroline, the defendant pled guilty to possessing between 150 and 300 images of child pornography, including two images of victim Amy from the "Misty" series, and Amy sought approximately $3.3 million in restitution under 18 U.S.C. § 2259 for her total losses from the initial abuse and ongoing circulation of the images. The district court denied the restitution request after two hearings and briefing. The court held that Amy qualified as a victim under the statute but that the government failed to prove by a preponderance of the evidence that any specific portion of her losses was proximately caused by Paroline's possession of the two images, as required by the statute's text linking restitution to harm resulting from the defendant's conduct. The opinion noted the practical difficulties of applying the restitution provisions to possession cases involving multiple unknown defendants.

In this patent case, IP Innovation and Technology Licensing Corporation sued Google for infringement of patents they acquired from Xerox through a settlement agreement that included assignment of the patents-in-suit. Google moved to dismiss for lack of standing, arguing that the agreement did not transfer all substantial rights in the patents to the plaintiffs, leaving Xerox and its subsidiary with too much retained control and economic interest. The court denied the motion, holding that the plaintiffs possessed both constitutional and prudential standing. The core reasoning was that the agreement expressly gave the plaintiffs the sole right to sue for infringement and recover damages, and the rights retained by Xerox were not substantial enough to reduce the transfer to a mere license.

This case involved i4i suing Microsoft for patent infringement, claiming that features in Word 2003 and Word 2007 for processing XML documents with custom XML elements violated U.S. Patent No. 5,787,449, which covers methods for separately manipulating a document's content and structure using metacode maps. A jury found the patent valid, infringed willfully, and awarded $200 million in damages. The court denied Microsoft's motions for judgment as a matter of law and new trials on issues including noninfringement, invalidity, damages, and indirect infringement, finding sufficient evidence supported the verdict under applicable legal standards. It granted i4i's motions for a permanent injunction, enhanced damages, attorneys' fees, and post-verdict interest, while also addressing equitable defenses like laches after a bench trial.

This case is a patent infringement lawsuit filed by Michael S. Sutton Ltd. against Nokia Corporation concerning U.S. Patent No. 5,771,238, titled 'Enhanced One Way Radio Seven Bit Data Network,' which covers methods and devices for sending 8-bit byte messages over radio paging networks limited to 7-bit messages. The court first construed disputed claim terms from claims 1 and 3, such as 'control message,' 'stuffing,' and 'sub-channel number,' relying primarily on the intrinsic evidence of the patent claims, specification, and prosecution history. Nokia moved for partial summary judgment on indefiniteness, enablement, and utility, and the court granted that motion while denying Nokia's separate motion to strike an expert declaration, finding the declaration unhelpful but not striking it.

This case is a patent infringement action in which Retractable Technologies, Inc. accused Occupational & Medical Innovations, Ltd. of infringing U.S. Patent Nos. 6,572,584 and 7,351,224, which describe syringes featuring spring-loaded retractable needles triggered by plunger contact after injection. The district court issued a Markman ruling construing disputed claim terms, including those relating to the plunger's front tip shape, the separation of the needle holder components via interference fit or bridge fracture, and mechanisms that ground or limit forward motion of the needle holder within the syringe barrel. The court derived the constructions from the ordinary meaning of the terms to a skilled artisan, guided primarily by the claim language itself, the shared patent specifications, and earlier judicial constructions of the same patents, while rejecting proposed limitations that lacked support in the intrinsic evidence.

In this patent infringement case, Fujitsu Ltd. sued Tellabs, Inc. and Tellabs Operations, Inc. in the Eastern District of Texas for allegedly infringing three U.S. patents related to optical communication systems. Tellabs had filed a related action in the Northern District of Illinois involving overlapping patents and technology, and it moved to transfer venue under 28 U.S.C. § 1404(a). The court granted the motion after analyzing private factors such as the convenience of witnesses, cost of attendance, and access to proof, along with public factors including local interest in the dispute. It concluded that the Northern District of Illinois was clearly more convenient and that transfer would promote judicial economy by consolidating the related cases before the same court.

Fenner Investments, Ltd. sued Microsoft Corp. and Nintendo for infringement of U.S. Patent No. 6,297,751, which covers a low-voltage joystick port interface allowing older 5-volt joysticks to connect to newer computers using lower-voltage CMOS circuits. The patent describes an interface that converts analog joystick signals into digital pulses whose widths represent coordinate positions. After claim construction, the court granted the defendants' motions for summary judgment of non-infringement. The ruling rested on the determination that the accused Xbox and Nintendo products did not satisfy key claim limitations, including the requirement that a single pulse width fully represent joystick position and the role of the processor in interpreting the signal.

This case involved a court-appointed receiver in a Commodity Futures Trading Commission enforcement action against a Ponzi scheme operator seeking to recover assets fraudulently obtained and transferred to third parties. The receiver petitioned for an order requiring Wendy Silette, an innocent recipient of funds from the scheme operator, to turn over her Florida condominium after she used over $300,000 of the funds to pay off its mortgage. The court granted the petition, imposing an equitable lien on the property and directing that it become a receivership asset subject to sale. The core reasoning was that Florida's homestead exemption does not bar equitable liens or forced sales where property was acquired or improved with fraudulently obtained funds, even when the current owner had no involvement in the fraud, as supported by state supreme court precedent and similar federal cases.
