Long-felt need

While we have focused extensively on unexpected results as one of the secondary considerations of nonobviousness, there are several additional considerations that can be argued. In this opinion, the Court addressed these several additional secondary considerations of nonobviousness as well. These additional important factors include commercial success, simultaneous invention, fulfillment of long-felt need, prior failure, others copying of the invention, third-party praise and recognition, and skepticism of persons skilled in the art. 

In the near future, the Preservation Office will be issuing a newsletter entitled, The National Preservation Report. The Preservation Office does this in response to a long-felt need and will attempt to provide news of preservation activities to the librarian, archivist, conservator, and scientist. 

This book would be of immense help to students at the postgraduate level as well as to research workers because of its contents and the way those have been dealt with. I sincerely hope that the book will go a long way to satisfy the long-felt need of students and teachers who inspire the students to take up synthetic organic chemistry as their research topic and career. 

The secondary considerations include commercial success, long-felt need, failure of others, copying, praise by persons in the industry, departure from accepted principles, and widespread recognition in the art of the invention s significance. 

Another, albeit weaker, approach is to argue from secondary considerations . It brings in such secondary considerations as the commercial success of the invention, that there was a long-felt need in the art for a solution to some problem, the failure of others to solve whatever problem the invention solves, and so on. 

A comprehensive manual on which the three Services have labored mightily for many years is in the process of being published while this manuscript is being prepared. It should fill a long-felt need. Two accessory parts of it have already appeared. L3. 32 ... 

Similar to treatment protocols of other chemical contaminants including arsenic, fluoride cannot be removed by typical water treatment means. Boiling, UV treatment, most methods of filtration, and most chemical treatment options are ineffective to remove fluoride from water. Synthetic ion exchange and precipitation processes, activated alumina filters, and reverse osmosis are typically used to remove fluoride from water in the developed world [5, 6]. There are no universally accepted used defluoridation techniques in the developing world with long felt need for development of appropriate technologies. 

This compilation of metal complex equilibrium (formation) constants and the corresponding enthalpy and entropy changes represent the authors selection of the most reliable values among those available In the literature. In many cases wide variations in published constants for the same metal complex equilibrium indicate the presence of one or more errors in ligand purity, in the experimental measurements, or in calculations. Usually, the nature of these errors is not readily apparent in the publication, and the reader is frequently faced with uncertainties concerning the correct values. In the course of developing noncritical compilations of stability constants, the authors have long felt that these wide variations in published work constitute a serious Impediment to the use of equilibrium data. Thus these critical tables were developed in order to satisfy what is believed to be an important need in the field of coordination chemistry. 

Protein chemists had long felt the need for an absolute standard for amino acids. In 1950, D-(+)-glyceraldehyde was converted, by genetic change in five steps, to D-( + )-serine. This showed that the (—)-serine, isolated from the hydrolysis of proteins, was L-(—)-serine. This result helped to fix all the amino acids of protein as members of the L-family, although some (such as alanine) show the ( + ) rotation (Brewster a/., 1950). 

My need for answers about the man—whichever man—was newer and sharper, a tinnitus of desire, than the dull bass note of my longing for Mark, which was so much part of me that I hardly felt it as something separate from myself, and it was a new, sharp struggle to ignore it.
