Editor's Note: A number of readers who have written to us of late may be disappointed in not seeing their letters appear in these columns. A vigorous Letters to the Editor department we feel contributes to C&EN's general goal of providing information and exchanging opinions.
However, correspondents should note we do not publish anonymous letters or letters that do not have both a signature and a return address we can verify. A typed name is not a "signature," and an address that is not complete enough for normal mail delivery is not a verifiable address.
Just as the editors accept responsibility for the entire magazine by listing their names on the masthead, so should correspondents accept responsibility for their letters with a signature and an address. While we do not normally publish addresses in these columns (and do publish an address where it seems necessary in light of the letter's content only after receiving the writer's prior approval), we do need an address for verification purposes.
To those who have contributed thoughtful letters in the past, our thanks; to future correspondents, a welcome to these pages.
European Patents DEAR SIR:
As a chemist who has spent many, many hours of his professional time on tedious and often pointless chores relative to patent matters, and who has come to think of our patent system as a burdensome, unfair, archaic, and self-defeating mess, the article "Common Patents for the Common Market" (C&EN, June 15, page 86) almost lets me hope that one day we may have a better world.
There are several things which, it seems to me, must be achieved if a better patent system is to be developed. The first concerns a clear, precise, and, insofar as is possible, non-subjective definition as to the purpose or purposes which the laws are intended to serve—that is, the philosophy behind the law. This definition must
not be taken as a mere rhetorical introduction to the subsequent individual articles, but as the guiding criterion for their design and interpretation. The drafting of this definition calls for men of the caliber of Jefferson and Adams.
Second, the notion that invention or novelty is that which cannot be predicted or anticipated by a person ordinarily skilled in the art must be scotched and be replaced by an empirical and nonsubjective basis. It is my opinion that here the scientists, engineers, and other technical persons must be consulted.
Third, the patent laws must be such as to prevent the granting of claims which are inadequately supported by experimental data and only gratuitous generalizations. Here, too, must the legal people work closely with the scientific and technical people.
Fourth, patents, to retain their validity, must be put to commercial usage within some reasonable period following their granting. This would reduce the number of "paper patents" that serve only to frustrate and obstruct further developments and improvements in the public's interest.

DEAR SIR: The special report, "Common Pat
ents for the Common Market" is a most timely and valuable study, which in view of our interests in foreign patent rights is most welcomed. The article is most comprehensive and does credit to your publication.
LEO J. BRANCATO Executive V.P., Heli-Coil Corp. Danbury, Conn.
DEAR SIR: . . . My impression from the press
in general is that the Common Market is not progressing toward any early conclusion, insofar as the trade and commercial aspects are concerned. Do you think that the Common Market will nevertheless proceed to put into effect the proposed "European" patent law?
If so, I suggest that the American
Representatives Throughout the World
•RTNI Du Pont Co. tRTM Union Carbide Corp.

representatives urge that the Common Market modify the requirements so as to enable countries outside the Common Market to apply for "European" patents. I fail to see the logic of establishing a European patent, and then confining it to the citizens of the Common Market countries, when a number of other countries might be very much interested to apply for such patents without being a member of the Common Market.

Ethics Code Superfluous? DEAR SIR:
As a new member of the ACS, add my vote to the 10% who feel a "code of ethics" should be avoided (see C&EN, July 13, page 102). I personally feel that a code of ethics similar to this is the basis for all people of the Judeo-Christian-Buddhist faiths. This leaves a very small minority of the membership of ACS unaccounted for. The very thought that one should need such a code outlined is in poor taste and reflects on the originator of such a thought (just as the Civil Rights Bill is a poor reflection on the character of the United States' brotherhood).
In a system based on logic, as chemistry is, is it not also logical that each adherent to the system would arrive at a similar code, not only for his professional life, but all of his life by his own reflection and meditation? Why, then, the need?

Desalting of Water DEAR SIR:
I was greatly interested in the article on reverse osmosis desalination of water (C&EN, July 20, page 48) . The laboratories of the city of San
Diego, Calif., have had occasion for work with the product from two methods of desalination—the first being from the Point Loma demonstration plant recently dismantled and shipped to Cuba and the second from the reverse osmosis method announced by Dr. Glenn Havens at San Diego on April 21, 1964.
The article covering the Aerojet General process would lead one to believe that the effluent water from this process is a potable water since it contains "200 p.p.m. dissolved salt" and "The U.S. Public Health Service's suggested maximum salt content of water for human consumption is 500 p.p.m." This statement is in error unless the term "salt" is used in its pure chemical sense. The USPHS standards use the terms "total solids" and "total dissolved solids" rather than "salt content."
This may look like the greatest case of "nit picking" on record but our experience with reverse osmosis effluent leads me to believe that under certain conditions it would be possible to be well within the USPHS total solids limit of 500 p.p.m. and still exceed the recommended limit of 250 p.p.m. for chloride.

Progress at Ole Miss DEAR SIR:
We are indeed grateful for your reporting of our staff additions (C&EN, July 20, page 76) . . . . Such considerate treatment is in sharp contrast to that of many otherwise objective people who are making our difficult task needlessly more difficult.
Our experience has been that visiting skeptics leave with a very favorable impression of us. Unfortunately this route would make for slow progress, so it is particularly refreshing to be given encouragement rather than condemnation.
To quote one of my colleagues, "While it is fool-hardy to believe that the social revolution does not have a direct effect on intellectual pursuits, it is equal folly to believe that what we do as educators and scientists will not influence the social character of the society."
