    Direct Listings and the Weakening of Investor Protections

    In 2018, the New York Stock Exchange (NYSE) amended its rules to allow a company to directly list on the Big Board without engaging in an initial public offering (IPO). This process-called a direct listingallowed a company to list its stock faster and cheaper, and, at least theoretically, at a more accurate price when compared to the traditional IPO. However, this first version of the NYSE\u27s direct listing rule only allowed the company to list, not raise capital. This limited its usefulness to companies. In 2020, the NYSE again amended its rules, this time to allow a company to list and raise capital. Commentators called this new-andimproved direct listing a game changer because it did away with any shortcoming (i.e., inability to raise capital) associated with the prior 2018 direct listing rule. In short, the direct listing could overtake the IPO in coming years. The primary claim of this Article is that when the SEC approved direct listings (the SEC must approve all rule changes proposed by the NYSE), it improperly put the advantages to companies before investor protection. While the SEC should give significant weight to a proposed rule change\u27s advantages to companies, it should not use such weighing to countenance the weakening of core investor protections. Yet, by approving direct listings in 2018 and approving the broader use of direct listings in 2020, the SEC did countenance the weakening of core investor protections. First, direct listings are underwriter-less. There is no traditional underwriter to serve as a gatekeeper to prevent insiders from foisting troubled companies on the public at inflated valuations. Second, if investors are harmed, there are fewer remedies available. One of the primary remedies for harmed investors-Section 11 of the Securities Act-is largely unworkable in the context of a direct listing. The repercussions of the SEC\u27s approval of direct listings are already beginning to show. Pirani v. Slack involves a Section 11 action brought by investors who purchased shares in Slack Technologies Inc.\u27s direct listing. The Northern District of California found that the investors could pursue their claim despite being unable to trace their shares to the direct listing (a holding contrary to IPO precedent), and the Ninth Circuit affirmed the holding. However, Slack has announced it is going to petition the Supreme Court for certiorari. Further, with the number of direct listings growing exponentially (one in 2018, one in 2019, two in 2020, and four in 2021), more such cases are undoubtedly on the way. Important Note to the Reader: This Article contains a postscript to address two significant events that occurred in December 2022, just prior to publication: the New York Stock Exchange further amended its direct listing rules to require underwriters in some circumstances, and the Supreme Court agreed to hear Pirani v. Slack

    Food for Thought: Genetically Modified Seeds as De Facto Standard Essential Patents

    For several years, courts have been improperly calculating damages in cases involving the unlicensed use of genetically-modified (GM) seed technology. In particular, when courts determine patent damages based on the hypothetical negotiation method, they err in exaggerating these damages to a point where no rational negotiator would agree. In response, we propose a limited affirmative defense of an implied license due to the patent’s status as a de facto standard essential patent. To be classified as a de facto standard essential patent, the farmer must prove three elements that reflect the peculiarities of GM seeds used in farming: (1) dominance, (2) impracticability, and (3) necessary to fulfill a basic need. Based on the approaches used by courts and standard setting organizations in licensing standard essential patents in technological fields such as cell phones and software, designation of some GM seeds as standard essential patents allows the courts to imply a license from patentees to farmers on reasonable and non-discriminatory (RAND) terms. Doing so shifts the case from a tort-based patent infringement suit to a breach of contract dispute and alters the damages regime from one based in compensation, deterrence, and punishment (a tort approach) to one based solely in compensation (a contractual approach). As a result of this novel proposal, the damages calculations in these suits return to economic reality

    Prevalent, protective, and convergent IgG recognition of SARS-CoV-2 non-RBD spike epitopes

    The molecular composition and binding epitopes of the immunoglobulin G (IgG) antibodies that circulate in blood plasma following SARS-CoV-2 infection are unknown. Proteomic deconvolution of the IgG repertoire to the spike glycoprotein in convalescent subjects revealed that the response is directed predominantly (>80%) against epitopes residing outside the receptor-binding domain (RBD). In one subject, just four IgG lineages accounted for 93.5% of the response, including an N-terminal domain (NTD)-directed antibody that was protective against lethal viral challenge. Genetic, structural, and functional characterization of a multi-donor class of “public” antibodies revealed an NTD epitope that is recurrently mutated among emerging SARS-CoV-2 variants of concern. These data show that “public” NTD-directed and other non-RBD plasma antibodies are prevalent and have implications for SARS-CoV-2 protection and antibody escape

Their biotrophic nature precludes many established molecular genetic manipulations and lines of research. The generation of genomic resources for these microbes is leading to novel insights into biology such as interactions with the hosts and guiding directions for breakthrough research in plant pathology. Results. To support gene discovery and gene model verification in the genome of the wheat leaf rust fungus, Puccinia triticina (Pt), we have generated Expressed Sequence Tags (ESTs) by sampling several life cycle stages. We focused on several spore stages and isolated haustorial structures from infected wheat, generating 17,684 ESTs. We produced sequences from both the sexual (pycniospores, aeciospores and teliospores) and asexual (germinated urediniospores) stages of the life cycle. From pycniospores and aeciospores, produced by infecting the alternate host, meadow rue (Thalictrum speciosissimum), 4,869 and 1,292 reads were generated, respectively. We generated 3,703 ESTs from teliospores produced on the senescent primary wheat host. Finally, we generated 6,817 reads from haustoria isolated from infected wheat as well as 1,003 sequences from germinated urediniospores. Along with 25,558 previously generated ESTs, we compiled a database of 13,328 non-redundant sequences (4,506 singlets and 8,822 contigs). Fungal genes were predicted using the EST version of the self-training GeneMarkS algorithm. To refine the EST database, we compared EST sequences by BLASTN to a set of 454 pyrosequencing-generated contigs and Sanger BAC-end sequences derived both from the Pt genome, and to ESTs and genome reads from wheat. A collection of 6,308 fungal genes was identified and compared to sequences of the cereal rusts, Puccinia graminis f. sp. tritici (Pgt) and stripe rust, P. striiformis f. sp. tritici (Pst), and poplar leaf rust Melampsora species, and the corn smut fungus, Ustilago maydis (Um). While extensive homologies were found, many genes appeared novel and species-specific; over 40% of genes did not match any known sequence in existing databases. Focusing on spore stages, direct comparison to Um identified potential functional homologs, possibly allowing heterologous functional analysis in that model fungus. Many potentially secreted protein genes were identified by similarity searches against genes and proteins of Pgt and Melampsora spp., revealing apparent orthologs. Conclusions. The current set of Pt unigenes contributes to gene discovery in this major cereal pathogen and will be invaluable for gene model verification in the genome sequence

    Incorporating clinical guidelines through clinician decision-making

    <p>Abstract</p> <p>Background</p> <p>It is generally acknowledged that a disparity between knowledge and its implementation is adversely affecting quality of care. An example commonly cited is the failure of clinicians to follow clinical guidelines. A guiding assumption of this view is that adherence should be gauged by a standard of conformance. At least some guideline developers dispute this assumption and claim that their efforts are intended to inform and assist clinical practice, not to function as standards of performance. However, their ability to assist and inform will remain limited until an alternative to the conformance criterion is proposed that gauges how evidence-based guidelines are incorporated into clinical decisions.</p> <p>Methods</p> <p>The proposed investigation has two specific aims to identify the processes that affect decisions about incorporating clinical guidelines, and then to develop ad test a strategy that promotes the utilization of evidence-based practices. This paper focuses on the first aim. It presents the rationale, introduces the clinical paradigm of treatment-resistant schizophrenia, and discusses an exemplar of clinician non-conformance to a clinical guideline. A modification of the original study is proposed that targets psychiatric trainees and draws on a cognitively rich theory of decision-making to formulate hypotheses about how the guideline is incorporated into treatment decisions. Twenty volunteer subjects recruited from an accredited psychiatry training program will respond to sixty-four vignettes that represent a fully crossed 2 × 2 × 2 × 4 within-subjects design. The variables consist of criteria contained in the clinical guideline and other relevant factors. Subjects will also respond to a subset of eight vignettes that assesses their overall impression of the guideline. Generalization estimating equation models will be used to test the study's principal hypothesis and perform secondary analyses.</p> <p>Implications</p> <p>The original design of phase two of the proposed investigation will be changed in recognition of newly published literature on the relative effectiveness of treatments for schizophrenia. It is suggested that this literature supports the notion that guidelines serve a valuable function as decision tools, and substantiates the importance of decision-making as the means by which general principles are incorporated into clinical practice.</p
