Restoring the Fact/Law Distinction in Patent Claim Construction
Two decades ago, the Supreme Court sought to promote more effective, transparent patent litigation in Markman v. Westview Instruments by ruling that “the construction of a patent, including terms of art within its claim, is exclusively within the province of the court.” In so doing, the Court removed interpretation of patent claims from the black box of jury deliberations by holding that the Seventh Amendment right to a jury trial did not extend to patent claim construction. Failing to find clear historical evidence of how claim construction was handled in 1791, the Court turned to “the relative interpretive skills of judges and juries and the statutory policies that ought to be furthered by the allocation.” It concluded that federal district court judges were better equipped than juries to resolve the mixed fact/law controversies inherent in construing disputed patent claim terms, thereby leading to more effective and transparent patent litigation. Fully achieving the Court’s goal of more effective and transparent patent litigation, however, depends on district judges having the flexibility to learn pertinent facts, build a reviewable record, and explain the basis for their claim constructions
Anesthetic Evaluation and Perioperative Management in a Patient with New Onset Mediastinal Mass Syndrome Presenting for Emergency Surgery
Mediastinal mass syndrome (MMS) is a complex case that poses many challenges to the anesthesiologist. The cornerstone of management focuses on the potential hemodynamic changes associated with this syndrome. We describe the anesthetic management of a patient with a previously undiagnosed mediastinal mass presenting for emergency neurosurgical surgery
Oxandrolone Improves Height Velocity and BMI in Patients with Cystic Fibrosis
Objective. To evaluate the effectiveness of oxandrolone in improving the nutritional status and linear growth of pediatric patients with cystic fibrosis (CF).
Methods. Medical records of patients with CF treated with oxandrolone were reviewed for height z score, height velocity (HV), BMI z score, weight velocity (WV), Tanner stage, pulmonary function, liver enzyme levels, and any reported adverse events. Data were compared before (pre-Ox) and after (Ox) oxandrolone using a paired t-test.
Results. 5 subjects (ages 8.5–14.5 years) were treated with oxandrolone 2.5 mg daily for 8–38 months. After 8–12 months of treatment, there was a statistically significant improvement in HV (pre-Ox = 5.3 ± 1.4 cm/yr, Ox = 8.3 ± 1.2 cm/yr, P < .01) and BMI z score (pre-Ox = −0.61 ± 1.04, Ox = −0.30 ± 0.86, P = .02). Both height z score (pre-Ox = −1.64 ± 0.63, Ox = −1.30 ± 0.49, P = .057) and WV (pre-Ox = 4.2 ± 3.7 kg/yr, Ox = 6.8 ± 1.0 kg/yr, P = .072) showed beneficial trends that did not reach statistical significance. No adverse events were reported.
Conclusions. In this brief clinical report, oxandrolone improved the HV and BMI z score in patients with CF. Larger studies are needed to determine if oxandrolone is an effective, safe, and affordable option to stimulate appetite, improve weight gain, and promote linear growth in patients with CF
