This is an application for a writ of mandate to compel the respondents, as members of and constituting the board of public works of the city of Los Angeles, to execute a contract for the improvement of certain streets and to pass upon the form and sufficiency of the bonds required in connection with said contract.
On the fourth day of September, 1925, the city council commenced proceedings to improve Orlando and other streets, electing to proceed under the provisions of the Improvement Act of 1911 (Stats. 1911, p. 730). The requirements of the statute were complied with and the petitioner was awarded the contract for the improvement of said streets, which was the paving thereof. Thereafter, on December 14, 1925, the petitioner presented a contract in due form, together with the necessary bonds, to the respondents for execution and approval. The respondents refused to execute and approve the same on the ground that they *137 entertained doubt as to whether the requirements of subdivision (10) of section 3 of the city charter with reference to the use of patented paving material had been fully complied with. Hence this proceeding.
The street improvements in question contemplate the use of a patented paving material known as the National Pavement Wearing Surface, the letters patent of which are owned by the National Pavements Corporation of California, a corporation. The city charter, in section 386 thereof, contains a general authorization to the city to enter into contracts for the purchase of articles covered by letters patent granted by the United States without competitive bidding, but with reference to the use of patented paving material the charter contains the following special provision :
“No pavement protected by any patent, trade-mark, trade name, copyrighted name, or any device which tends to prevent competitive bidding, shall be ordered by the city, until the owner thereof has entered into a written agreement with the city transferring to the city all right to the use of the same within the city upon the terms and conditions set forth therein. The city shall not be bound by any such agreement unless the same shall have been approved by the Board of Public Works, two-thirds vote of the Council, and the Mayor, and executed by the Mayor on behalf of the city. No such agreement, shall be for a longer period than five years.
“Whenever the city shall let a contract for the construction of any such pavement the contractor therefor shall pay to the city the exact sum or royalty which the City is required to pay under its said agreement.
“Whenever the city shall construct any such pavement by the direct employment of labor and purchase of materials, the costs of which are chargeable upon the property in a special assessment district, the exact sum or royalty which the city is required to pay under said agreement shall be added to and included in the costs chargeable to the property in said special assessment district.” (Charter, art. I, sec. 3, subd. [10], Stats. 1925, p. 1037.)
With the requirements of the foregoing charter provision in view, the National Pavements Corporation of California, on July 21, 1925, executed what is called a National Pave *138 ments License Mixture Agreement. This agreement, so far as material here, provides that whereas it is deemed advisable by the proper authorities of the city of Los Angeles that certain streets in the city be paved with National Pavements in accordance with specifications numbered 129, new series (wherein this and other patented paving materials are specified for street paving), and that competitive bidding is deemed advisable, and that whereas said corporation is the owner of all the patents and processes covering such National Pavements wearing surface in the state of California: “Now, therefore, National Pavements Corporation of California hereby agrees to transfer, and does transfer to the City of Los Angeles all right to the use of said patented pavement and all of the patents, trade marks, trade names and copyrighted names now owned, or which may be hereafter owned by said National Pavements Corporation of California, necessary to the use of the said National Pavements pavement constructed in accordance with said specifications, and pursuant to this agreement. And for the consideration hereinafter named, and in and for the consideration of the adoption by the City Council of the City of Los Angeles of Resolution or Ordinance of Intention, and such other proceedings as may be necessary to provide for the improvement of any one or more of the said streets, avenues, boulevards, places, courts, public ways, rights of way, lanes, alleys, and properties, in said city, or forming a part of the boundaries thereof, whether lying within or without said city, in accordance with the above named specifications, National Pavements Corporation of California hereby proposes and agrees to furnish to the City of Los Angeles for all work or improvement of paving any one or more of the said streets, avenues, boulevards, places, courts, public ways, rights of way, lanes, alleys, and properties, in said city, or forming a part of the boundaries thereof, whether lying within or without said city, with said National Pavements pavement, and to any contractor to whom may be awarded the contract for such work or improvement and to the owners of lots and lands proposed to be assessed for said work or improvement who may elect to take the work and enter into a contract to perform the same as 1 contracting owners, ’ and for which an Ordinance or resolution of Intention has been regularly adopted by the City Council of said City of Los *139 Angeles at any time within four (4) months from date hereof, or at any time thereafter until this offer is withdrawn by the undersigned by a thirty (30) day written notice filed with the City Council of the City of Los Angeles, the following material manufactured and mixed ready for laying as specified and required under and by said specifications, and services, with the right to use any or all of the patents, trade marks, or trade names now owned or which may be hereafter owned by said National Pavements Corporation of California, necessary to lay said pavements :” The material specified in the agreement is described as “the necessary paving mixture for the wearing surface prepared under the patents and processes of National Pavements Corporation of California and in accordance with the said specifications of the city of Los Angeles above referred to, delivered at the temperature specified in said specifieatons in wagons or trucks of the contractor or purchasers of said mixture at National Pavements mixing plant in the City of Los Angeles. ” It is also provided that an expert whose time and expenses will be paid for by National Pavements Corporation will be furnished to the purchaser of said mixture at the expense of the corporation, and frequent tests of the mixture will be made by said expert so as to insure uniformity and best results. The prices at which the material may be obtained by any successful bidder are fixed at from nine cents to eleven and one-half cents per square foot of wearing surface, according to thickness. The term of the agreement is fixed at five years from its date. The agreement then provides: “The execution of any work or improvement by the successful bidder or ‘contracting owners’ and the City of Los Angeles, or department thereof, shall be deemed by the said National Pavements Corporation of California to be an acceptance of this proposal by the City of Los Angeles and- shall bind the undersigned National Pavements Corporation of California to furnish said rights, materials and services to whom the contract to perform the work or improvement contemplated in the said Ordinance or resolution of Intention is let.” ■ The agreement was duly executed by the National Pavements Corporation of California, was approved by a majority vote of the board of public works, by a two-thirds vote of the city council, and was executed on behalf of the *140 city by its mayor as required by the foregoing charter provision.
As disclosed by their verified answer the respondents contend that said charter provision requires the license agreement to transfer not only the right to “use” the patented material, but also “to make available to all contractors engaged in public improvement work and who desire to bid and enter into contracts for such work, a similar right to manufacture, sell and lay such patented pavement.” The transfer of the right to sell is not now pressed but it is particularly urged that the right to “use” as that word is employed in the charter provision includes the right to “manufacture.”
Section 8 of article I of the constitution of the United States provides that the Congress shall have power to promote the progress of science by securing for limited times to inventors the exclusive right to their inventions. In pursuance of this constitutional provision Congress has provided, among other things, that there shall be granted to the patentee, his heirs or assigns,- for the term of seventeen years, the exclusive right to make, use, and vend the patented article throughout the United States (U. S. Comp. Stats. 1916, sec. 9428; Rev. Stats., sec. 4884). The patent, therefore, grants to the patentee three exclusive rights; first, “to make,” second “to use,” and third, “to vend” the patented article. That the holder of a patent has these three separate and distinct rights was declared by the supreme court of the United States in
Adams
v.

The subject of the purchase of patented articles by municipalities in this state has received consideration in several cases.
(Nicholson Pavement Co.
v.
Painter,
When we approach the Los Angeles provision in the light of the foregoing considerations we find that it is therein required that before any pavement protected by letters patent, etc., shall be ordered by the city the owner of the patent rights shall enter "into an agreement with the city” transferring to the city "all right to the use” of the patented paving material within the city "upon the terms and conditions” set forth in the agreement. The terms and conditions to be specified in the agreement are safeguarded by the requirements that the agreement "be
*143
approved by a majority vote of the Board of Public Works, two-thirds vote of the Council and the Mayor,” which requirements were complied with in this case. No reference is made in the charter to the transfer of the right to manufacture. A determination that the owner of the patent must in said agreement specifically transfer to the city the right to manufacture the patented article would be justified only on the theory that the charter provision so requires. It does not do so in express language and we find no expression therein which would support the conclusion that it does so by necessary or reasonable implication. The charter provision is, of course, subject to the same rules of interpretation as a statute. If it be free from ambiguity no construction or interpretation is required or permissible and it must be given no meaning other than its words import. “It is a cardinal rule applicable to the interpretation of statutes that in order to ascertain the intent of the legislature in enacting the same, recourse must first be had to the language of the statute itself; and that if the words of enactment given their ordinary and proper signification are reasonably free from ambiguity and uncertainty, the courts will look no further to ascertain its meaning.”
(People
v.
Stanley,
*144 For the purpose of indicating circumstances which might justify the court in so holding, the respondents in their answer allege that if the city or any successful bidder or the property owners in the assessment district are to receive any substantial benefits from the requirements of the charter provision it must be held that the right “to use” includes the right “to manufacture.” It is alleged that the petitioner and many other contractors engaged in the paving contracting business “own, possess or control various paving mixtures patented or otherwise protected under the laws of the United States, or possess an exclusive right and license for the use of such patents and such patented paving mixtures”; that the petitioner and such other contractors possessing such rights are enabled to charge and exact from property owners and others required to pay assessments for street paving excessive and exorbitant amounts for the use of such patented paving material, and that the specification of such materials in assessment work without a license agreement to make and use the patented materials results in the creation of a monopoly and of the opportunity to charge unfair, unreasonable, and exorbitant prices for such pavements, and further results in favoritism in the securing of contracts and prevents competition at the expense of property owners who are assessed and required to pay for such patented paving. It may be that the framers of the charter provision had in mind the prevention or correction of some or all of the alleged abuses. If so the question arises, was the result fully accomplished by the particular charter provision adopted? For aught that appears in the record herein it would seem that in so far as the charter provision and the license agreement executed pursuant thereto make available to the city and all bidders on such public work the use of such patented material at a fixed and uniform price the purpose has been accomplished. If the full purpose suggested by respondents has not been accomplished it may be noted that there appears to be no obligation on the part of the city to specify such patented material to be used in work to be done either by the city itself or under the assessment district plan. There is likewise no compulsion on the part of property owners to petition for any particular kind of patented pavement as was done in this case, and if the board of public works *145 should conclude upon the consideration of the bids that the prices specified by the bidder are unfair or exorbitant or the proceeding is tainted with favoritism it has the power under the statute to reject any and all bids should it deem this for the public good (sec. 10, Stats. 1911, p. 735).
The respondents state that in framing the said charter provision the board of freeholders had before it the provisions of the charter of the city and county of San Francisco and the case of
Warren Bros. Co.
v.
Boyle,
It is further stated by the respondents that the framers of the Los Angeles charter provision 'had in mind the ruling of the supreme court of Wisconsin in the case of
Allen
v.
Milwaukee,
In further support of their contention that it was intended by the said charter provision that the municipal authorities should be limited in the specification of patented pavement to the acquisition of “an unlimited license,’’ which in the language of the answer would include the right on the part of the contractor “to manufacture, sell and lay such patented pavement, ’ ’ it is urged by respondents that unless the successful bidder has the right to make the paving material no benefit would accrue from the right to use the same, as anyone could purchase the material and with the purchase the right to use it would necessarily follow. It may be assumed that the self-interest of the owner of a patented article would prompt him to market his product notwithstanding his legal right to withhold it from the market or to refuse to sell it to anyone
(Heaton-Peninsula etc. Co.
v.
Eureka Utility Co.,
The respondents urge that in other respects the said license agreement is not in accordance with the charter requirements. We are of the opinion, however, that in so far as the charter provision may be said to apply to the special proceeding in question the license agreement is in compliance therewith.
It is alleged in the petition that numerous paving materials protected by patents, trademarks, trade names and copyrighted names have been used by the city of Los Angeles; that numerous materials and articles protected by patents, etc., other than paving materials so protected, are *151 now being specified and used by said city in the construction and improvement of streets, such as ornamental lighting systems, patented interlocking brick, patented cement sewer-pipe, vitrified pipe, sewer-flushing devices and many other materials and devices- that no license agreement relative to the use of any such articles or materials so protected by letters patent, etc., has been or is required by the city; that during the year 1925 patented lighting posts and equipment were installed by the city of Los Angeles at a cost aggregating more than two and one-half million dollars, and that the owners of the patents on such lighting posts and equipment are not required by the charter of the city to execute a license agreement such as is imposed on the owners of patented paving material. These allegations are not denied by the respondents, and the petitioner predicates thereon an argument that said subdivision (10) of section 3 of the Charter is unconstitutional for the reason that the same constitutes an unjust and unreasonable and unlawful discrimination against the owners of patented paving materials, entitled under the law to sell their goods, and in favor of owners of patents on other articles and materials purchased by the city. We deem it unnecessary to pass upon the points thus urged for the reason that we have concluded that the license agreement in question is in compliance with the charter provision as above indicated. Other points made by the respective parties have been considered. In view of what has been decided we also deem it unnecessary to mention or to pass upon them specifically.
Let the peremptory writ issue as prayed.
