Patent and Place: Intellectual Property and Site-Specificity Richard L Hindle Introduction Reviewed by Diana Balmori Among the more than 9 million U.S. patents granted since the Patent Act of 1790, a representational anomaly exists in which intellectual property and place converge in an evocative yet confounding hybrid at the interstices of technology and environment. For good reasons, known geographical locations are rarely represented in patent documents. The specificity of place precludes the widest interpretation of patent claims and is, therefore, generally omitted from texts and images that aim to protect the broadest interpretation of intellectual property. Besides, direct correlation between the configuration and function o f a n o v e l i n v e n t i o n a n d a s p e c i fi c l o c a t i o n , l a n d s c a p e, or environmental condition is atypical—obviously. Yet, the schism between patent and place is not absolute, and a unique subset of patents granted by the U.S. Patent and T r a d e m a r k O f fi c e ( U S P T O ) i n c l u d e s t e x t s a n d i m a g e stha suggest site specificity within intellectual property claims.

Patent, Representation, and Environment Patents have operated as an invisible landscape-of-power in the built environment since the Italian Renaissance, w h e n t h e w o r l d ’ s fi r s t p a t e n t w a s i s s u e d t o t h e e minet architect Filippo Brunelleschi in 1421 for a “machine or ship” and method of transporting materials for his Duomo of Florence, establishing seminal legal and architectural precedents.1 Brunelleschi’s patent protected his invention of a new machine and method for transporting heavy loads by water, solving one of three major engineering problems associated with his novel dome construction processes.2 Although the patent’s legalese and the dome’s structure operated independently on discrete legal and structural principles, they formed together a highly interdependent and deterministic mechanism governing the form of the built environment. In this manner, the patent—western civilization’s oldest legal and institutional mechanism for i n c e n t i v i z e d i n n o v a t i o n — h a s l o n g m i r r o r e d , d e fi n e d , a n d shaped the built environment, yet failed to represent it eidetically in a way that is commonly recalled.3 Patents do parallel the built environment and thinking. In his book The New Architecture and the Bauhaus ( 1 9 3 5 ) , t h e m o d e r n i s t a r c h i t e c t a n d t h e o r i s t W a l t e r Gropius foretold the transformation of architecture and design through industrial process, and, true to form, h e a n d h i s b u s i n e s s p a r t n e r K o n r a d W a c h s m a n n s e c u r e d a U.S. Patent for a “Prefabricated Building System” ( U S 2 3 5 5 1 9 2 ) i n 1 9 4 2 , a p p l y i n g B a u h a u s p r i n c i p l e s t o contemporary housing problems.4 Just a few years earlier, i n 1 9 3 8 , S t a n l e y H a r t W h i t e , a p r o f e s s o r o f l a n d s c a p e a r c h i t e c t u r e a t t h e U n i v e r s i t y o f I l l i n o i s , u n i fi e d n e w steel structural principles with advances in hydroponic technology to create a vertical garden model called the “Vegetation Bearing Architectonic Structure and System.” Correlating modern landscape theory to U.S. Patent claims, W h i t e ’ s i n v e n t i o n w a s a t r u l y m o d e r n a c c o m p l i s h m e n t i n forty-five.com / papers /139 the context of academic Beaux Arts.5 This coevolution of patent development and the built environment can also be traced through other complex infrastructural and natural systems, such as rivers, coasts, cities, buildings, and designed landscapes.6 A p a t e n t i s , i n e s s e n c e , a r e p r e s e n t a t i o n o f a s p e c i fi c invention. U.S. patents have been accompanied by models, drawings, and textual descriptions since the Patent Act of 1790, which established American patent law and pertinent representational standards.7 The Patent Act states that grantees shall deliver to the Secretary of State, Secretary o f W a r , a n d A t t o r n e y G e n e r a l “ a s p e c i fi c a t i o n i n w r i t i n g, containing a description, accompanied with drafts or m o d e l s , a n d e x p l a n a t i o n s a n d m o d e l s ( i f t h e n a t u r e o f t h e i n v e n t i o n o r d i s c o v e r y w i l l a d m i t o f a m o d e l ) o f t h e t h i n g or things, by him or them invented or discovered.” If the invention was found to be new and valuable by the cabinet secretaries and the Attorney General, the patent was granted and signed, bearing ultimately the “teste” of the President himself. In that manner, the government and inventors coevolved the technological substrate of “the arts” towards unforeseen ends. Patent law places no restriction on what may be invented or what might be deemed useful or valuable among the arts, opening up a world of possibilities limited only by the ingenuity of the citizenry and the representational standards of the patent, which today is global, territorial, nanoscale, atmospheric, and even a s t r o n o m i c a l i n r e a c h ( fi g u r e s 1 a - b ). Most patents related to landscapes, rivers, cities, regions, coastlines, and other complex environmental systems are intentionally site-less, distancing intellectual property c l a i m s f r o m a n y s p e c i fi c l o c a t i o n s . P a t e n t s o f t h i s s ort typically use diagrammatic or typological drawings to disclose inventions and protect the widest possible scope of intellectual property claims while maintaining ambiguity as t o w h e r e t h e p a t e n t m i g h t b e a p p l i e d ( fi g u r e s 2 a - f ) . T h o se drawings cover a range of design thinking and processes— describing workflows, evaluative methods, detailed material configurations, gadgets of one kind or another, and a dizzying array of objects—ultimately representing the environment as a series of typological conditions, tectonic assemblages, data sets, and operations often contingent o n s p e c i fi c s p a t i a l o r p h y s i c a l c o n d i t i o n s y e t , i n e s s enc, without specific sites. The siteless quality of environmental patent documents does not diminish their potential impact on large-scale complex systems. Consider, for example, the design and construction of Eads’ Jetties at the South Pass of the Mississippi River, near Fort Jackson, a patented system r e a l i z e d b e t w e e n 1 8 7 5 a n d 1 8 7 9 a n d c r e d i t e d w i t h saving the Port of New Orleans by sustaining commercial a c t i v i t i e s a l o n g t h e M i s s i s s i p p i ( fi g u r e s 3 a - c ) . J a m es Buchannan Eads and his business partner James Andrews prototyped and tested their jetty system at full scale for four years before receiving their fee for the maintenance of a navigable channel at the mouth of the Mississippi, r a d i c a l l y a l t e r i n g t h e fl u v i a l g e o m o r p h o l o g y a n d e c o l ogy at the Head of Passes.8 The patent granted to Eads and Andrews was designed to suit the unique conditions at the Heads of Passes, yet the document itself makes no mention o f t h i s s p e c i fi c l o c a t i o n , r e f e r e n c i n g o n l y e n v i r o n m e ntal conditions common to deltaic landscapes and a method o f c o n s t r u c t i o n . W e k n o w o f t h e p a t e n t ’ s u s e t h r o u g h Eads’ petitions to Congress and detailed histories of the jetties, but the patent itself makes no reference to a known geographical location. Eads’ patent may be siteless, but i t s i m p r i n t o n a s p e c i fi c l a n d s c a p e i s b o u n d t o t h e f a b ricof culture and remains legible today in the morphology of the Mississippi River.

Speaking generally, the siteless quality of patents has obscured an intimate relationship between known places and s p e c i fi c t e c h n o l o g i e s .

Although patent cartographies usually lack the scale and graticule of conventional mapping, known locations are s o m e t i m e s c l e a r l y d e m a r c a t e d w i t h l a b e l s a n d i d e n t i fi a b l e boundaries. Not only can those places be recalled, known, or visited in the real world; they are also sites of technological innovation. As representations, the maps range in s p e c i fi c i t y f r o m s y s t e m s d i a g r a m s t h a t s i t u a t e a n i n v entio within a known location to detailed bathymetries that show the resultant geomorphology of a specific intervention. Examples include proposals for the removal of ice from New York Harbor and the East River, a passive dredge system for Galveston Bay, a hydroelectric plant for Niagara Falls that preserves scenery and produces power, and even current infrastructure/ecology hybrids designed to reinforce and cultivate mangrove ecosystems in Florida and around the world.10 W h a t i s t h e r e l a t i o n s h i p b e t w e e n p a t e n t c a r t o g r a p h i e s a n d k n o w n g e o g r a p h i c a l l o c a t i o n s ? S i t e s p e c i fi c i t y w i t h i n patents raises important questions about the extents and jurisdiction of patent law, in addition to challenging commonly accepted models for innovation in complex environmental systems. Take, for example, the life work o f L e w i s M . H a u p t ( 1 8 4 4 - 1 9 3 7 ) , a p r o f e s s o r o f c i v i l engineering at the University of Pennsylvania and, before that, a patent examiner at the USPTO.11 Haupt’s theories on the “Physical Phenomena of Harbor Entrances” earned him a Magellanic Premium award from the American Philosophical Society in 1887, and, on the same day that he accepted that award, he was granted a U.S. Patent for a “Dike or Breakwater,” which linked his design theories to known environmental conditions and specific locations.12 Following in the footsteps of Eads and others advancing American infrastructure through public/private partnerships, the “Reaction Breakwater,” as Haupt’s invention was popularly known, was to be prototyped at Aransas Pass, Texas, by the R e a c t i o n B r e a k w a t e r C o m p a n y u s i n g t h e s p e c i fi c a t i o n o f h i s p a t e n t ( fi g u r e s 6 a - c ) . A f t e r a r e v i s i o n t o t h e c o n trac, however, the Federal Government ultimately awarded the bid for construction to another company, which intended to b u i l d t h e b r e a k w a t e r p e r H a u p t ’ s s p e c i fi c a t i o n s . D u r i n g this process, Haupt’s patent was assigned to the U.S. Government for use at Aransas Pass. In turn, the Secretary o f W a r , r e s p o n s i b l e f o r o v e r s e e i n g i m p r o v e m e n t s i n r i v e r s and harbors, dismissed Haupt’s research and patent as “purely theoretical,” insisting that all of his discoveries w e r e “ u n c o n fi r m e d b y e x p e r i e n c e , a n d c o n t a i n n o t h i n gnot already well known, and which has a useful application in the improvement of our harbors.”13 T h e W a r D e p a r t m e n t ’ s attempt to discredit Haupt’s invention also inadvertently cast doubts on the American Philosophical Society’s Magellanic Premium, which Haupt defended tirelessly in lectures to the Society and through publications.14 Haupt eventually petitioned Congress for payment for partial use of his patented invention, but only after the debacle called into question the role of patent innovation in civic and public works under the jurisdiction of the federal government. Accusations of patent infringement and the botched construction process resulted in a lawsuit between Haupt a n d t h e S e c r e t a r y o f W a r , i n w h i c h r u l i n g t h e j e t t y w a s declared property of the U.S. Government and, therefore, not subject to intellectual property infringement. Haupt’s difficulties proposing innovations for works under the jurisdiction of the federal government and the Army Corps of Engineers did not dissuade him from further explorations, and he continued to develop patent proposals for places such as the Southwest Pass on the Mississippi River, following in E a d s ’ f o o t s t e p s o f t w e n t y - fi v e y e a r s e a r l i e r a t t h e S outh P a s s ( fi g u r e 7 ). 15 In the later years of Haupt’s career, he also consulted on the need for innovation in infrastructure and helped formulate a critique of new patent law that attempted to suppress patent innovation in civic works.16 Interestingly, by 1920, the federal government was involved i n fi f t e e n m i l l i o n d o l l a r s o f p a t e n t i n f r i n g e m e n t l a w suit, and several million dollars of suits related to improvements in rivers and harbors.17 Irrespective of the shifting landscapes of patent law, the ever expanding role of government in large-scale e n g i n e e r i n g w o r k s , o r t h e l a c k o f c l e a r fi n a n c i a l i n c e n t i v e s for works that preclude commodification, inventors and innovators attempted to reinvent the built environment and natural systems using the legal and institutional mechanisms of the patent. Today, this record provides an inductive view of environmental design thinking and a fruitful repository for future innovation studies. New tools may be needed to link patent innovation to place and the unique conditions, durations, and scales of complex environmental systems. For example, maps and other cartographic forms of representation are not the only i n d i c a t o r s o f s i t e - s p e c i fi c i t y i n t h e p a t e n t a r c h i v e . K now geographic locations are also sometimes described in textual claims and descriptions, even though the associated patent diagrams and drawings remain siteless. Mentions of known locations are especially easy to overlook. More than 9 million patents have been granted to date in the United States, and each of those contains many words—even into the tens of thousands—making textual searches for known l o c a t i o n s d i f fi c u l t .

Landscapes are not things, cities are not things, and coastal zones are not things, yet each is subject to the iterative and often deterministic forces of human ingenuity. In the following texts and images, I investigate site- specific patents that function at landscape and regional scales but with drawings and diagrams that are siteless and s c a l e l e s s .

In one drawing per patent, I adapt claims a n d t e c h n i c a l s p e c i fi c a t i o n s t o t h e g e o g r a p h i c a l l o c a tion described in the text, synthesizing historical research and maps with the “new” innovation disclosed in the patent. The texts and images presented here are, in their simplest form, ruminations on the intersections of place and intellectual property. They provide geographical context to patents that may have radically altered the American landscape, transcending the object-oriented history of patents to suggest a new hybrid at the intersection of technology and environmental geography of innovation.

A Medici Proposal for the Mississippi – US Patent 658,795 ( fi g u r e s 8 a - c) Juan Bautista Medici was born in Piedmont, Italy, in 1843 a n d d i e d i n B u e n o s A i r e s , A r g e n t i n a , i n 1 9 0 3 . W h i l e r e s i d i n g in Italy, he worked as an engineer on domestic railroad projects and the potable water network of Montevideo, Uruguay. After emigrating to in 1870, Medici became involved in the detailed survey of Buenos Aires. Later, together with the Argentine engineer Lavalle, he g r a d e d 1 7 5 , 0 0 0 s q u a r e k i l o m e t e r s o f t h e p r o v i n c e o f Buenos Aires. The latter was followed by the construction of an extensive network of channels to drain the area and the addition of two navigable channels. This project was awarded a gold medal at the Esposizione Italo-Americana i n G e n o a ( 1 8 9 2 ) . 19 During his illustrious career in Argentina, Medici was also involved in the layout, planning, waterworks, and construction of the capital of the province of Buenos Aires, La Plata.20 A t 5 7 y e a r s o l d , a n d a f t e r a lifetime’s work in civil and hydrologic engineering, Medici submited his patent to the USPTO with the intention of r e c o n fi g u r i n g t h e d e l t a o f t h e M i s s i s s i p p i River. 21 Medici intended for his invention to be a direct technological retort, or innovation, following Eads’ Jetties at the South Pass of the Mississippi. Medici claimed: T h e s y s t e m o f j e t t i e s o r a r t i fi c i a l i s l e t s f o r m e d o f b r u s hand earth employed, for example, in the delta of the Mississippi [referring to Eads’ Jetties] has fallen short of desired results, owing to the rigid nature of the resistance thus offered to the tremendous for of wave and current, before which force such rigid bodies must eventually give way. I have therefore sought to overcome the defects of such systems in the manner which I will now proceed to describe. Medici’s patent involves the anchoring of a subsurface “forest” or “orchard” of large, cut trees with variable d e p t h s r e l a t i v e t o t h e s u r f a c e t o g u i d e fl o w i n g w a t e r a nd c a p t u r e s e d i m e n t .

The system invites us to imagine a vast deltaic landscape constructed on principles observed in naturally dynamic deltaic landscapes, yet designed to meet human necessity for navigation. Medici’s proposed structure is expansive, potentially extending for miles, and would function at a s c a l e c o m m e n s u r a t e w i t h t h e d e l t a s o f l a r g e r i v e r s . W h e n compared with conventional technologies for engineering of navigable channels, such as jetties and breakwaters, Medici’s proposal neglects the singular object and, therefore, precludes object-oriented description, evoking instead various conditions found in nature or other large- s c a l e p r o d u c t i v e l a n d s c a p e s s u c h a s fi e l d , f o r e s t , o r c h a r d, p l a i n , i s l a n d , fi e l d , d e l t a , e tc.

Protecting Southern Louisiana’s Riparian Lands from O v e r fl o w – U S P a t e n t 4 8 8 ,42 ( fi g u r e s 9 a - b) Linus Weed Brown (1856-1910) was appointed assistant e n g i n e e r o f t h e C i t y o f N e w O r l e a n s i n 1 8 8 5 a n d c h i e f engineer in 1892. In those capacities, he completed detailed topographical surveys of the city, including studies of precipitation and run-off and detailed proposals for a drainage system.22 He later published a booklet summarizing the complex engineering works undertaken while he was a city engineer.23 Brown’s work on the drainage of New Orleans necessitated a comprehensive understanding of the Mississippi River levee system and the topography of the region. In 1892, just as he was appointed chief engineer for New Orleans, he was also granted a patent for a “ S y s t e m o f P r o t e c t i n g R i p a r i a n L a n d s f r o m O v e r fl o w , ” w h i c h a d v a n c e d t h e a r t o f fl o o d m a n a g e m e n t b y u s i ng outlets or “waste weirs” along the lower Mississippi.

Brown suggested that his system be implemented at Lake Brogne and Lake Maurepas, and at as many river b e n d s a s n e c e s s a r y t o d i s t r i b u t e fl o o d w a t e r s e f f e c t i v e l y . Although the primary purpose of Brown’s invention was t o p r o t e c t l o w - l y i n g l a n d s f r o m o v e r fl o w , i t m i g h t a lso have facilitated sediment recharge in a delta starved by levees. Boosters of the “levees only” policy ultimately discredited alternate proposals, including designed outlets such as Brown’s, even though critics knew that a levees o n l y s o l u t i o n t o fl o o d c o n t r o l w o u l d t o c o n t r i b u t e t ohe collapse and subsidence of the Mississippi River Delta.24 The weir plan was never implemented during the legal period of Brown’s patent. Interestingly, the Bonnet Carre Spillway, which employs a weir system to divert water to Lake Pontchartrain, was constructed after the devastating fl o o d s o f 1 9 2 7 s u b m e r g e d t h o u s a n d s o f a c r e s o f l a nd.That event occurred 39 years after Brown’s patent was granted and a decade after expert witnesses argued before Congress in favor of waste weirs similar to those Brown proposed for the Mississippi.25

Source/Sink Levee formation in California Delta – US Patent 235,967 ( fi g u r e s 1 0 a - b) On December 28, 1880, Newton Sewell (1821-1902), a county assessor and landowner in Yuba, California, w a s g r a n t e d U . S . P a t e n t 2 3 5 , 9 6 7, w h i c h d e s c r i b e s a passive hydraulic method for levee formation through the construction of check dams within sediment-laden rivers. The dams would divert accumulated sediment to a series of settling enclosures that in turn would become a levee. Sewell’s patent for a “Method of Relieving River-Channels of Sediment and Forming Levees” utilizes the energy of rivers, local topography, and river sediment of the gold rush to build levees in California’s Central Valley. The design is topographical in nature, correlating the slopes of rivers, dam sequences, and sediment enclosures to the locations of levees. Sewell’s invention was conceived in the later years of hydraulic dredging practices for gold mining in the upper reaches and tributaries to the Sacramento and San J o a q u i n D e l t a ( a k a t h e C a l i f o r n i a D e l t a ) — a m i n i n g p r o c e s s that almost choked the delta and San Francisco Bay with sediment. During this period, an estimated 300 million cubic meters of sediment were moved by rivers and creeks from the Sierra Nevada Mountains into the Central Valley and San Francisco Bay—enough material to cover 380 square miles at a depth of one foot. Sewell’s design is noteworthy not o n l y f o r i t s e n g i n e e r i n g o f t h e i n t r i n s i c fl u v i a l p r o c e s s e s of rivers and for linking levee formation to topographical change in river systems, but also for its mastery of regional source-sink sediment budgets in river systems by utilizing the sediment generated upstream, in the distant reaches of the Sierra Nevada Mountains to build levees downstream in the productive alluvial plains of the valley. Sewell also suggested that the system might be used to “reclaim,” or raise, low lying areas through the addition of sediment— an interesting and farsighted proposal given the massive subsidence in the delta today resulting from extensive levee construction, agriculture, and oxidation of rich organic soils. The process is quite simple, utilizing a series of low- crested check-dams to raise the level of water and divert sediment-laden water into settling enclosures, allowing for levee formation at an increased height relative to the original elevation of the river. Once the levee has formed and the dam is removed, the river elevation recedes to n o r m a l a n d t h e l e v e e r e m a i n s e l e v a t e d . W h e n e n v i s i o n e d serially along the reaches of a river system, a mosaic of leveed lands can be envisioned, similar to the natural bars and highlands formed intrinsically by migrating rivers. Importantly, the system was developed for implementation along the rivers of central California, between the gold rich lands of the Sierra Nevada and agriculturally productive lands of the California Delta, a statewide sediment management plan disclosed in patent.

Conclusion P a t e n t s h a v e i n d i r e c t l y m i r r o r e d a n d d e fi n e d t h e b u i lt e n v i r o n m e n t s i n c e t h e I t a l i a n R e n a i s s a n c e , w h e n t h e fi r s t true patent was issued to the architect Brunelleschi. As the founders of American Democracy pondered innovation and patents centuries later, they created a system to promote invention, limit monopolies, and expand the public domain of shared intellectual property, while simultaneously building a new nation. The potential for environmental transformation implicit in new technologies was well understood by Jefferson and others, yet the future permutations of technology and environment remained indeterminate and unforeseen. Importantly, the authors o f t h e C o n s t i t u t i o n ( 1 7 8 7 ) a n d t h e s u b s e q u e n t P a t e n t Act of 1790 put few limits on what may be patented,26 which liberated the creative spirit of a citizenry to evolve all sectors of “the arts,” including the lesser-known environmental arts. Many important questions are raised by the curious reciprocity between patents and the built environment, including the potential for innovative new i d e a s t o t r a n s f o r m p l a c e s . T h e a n o m a l y o f s i t e - s p e c i fi c i t y within patents is only one rhetorical and historical framework through which to explore the environmental arts. W i t h i n t h i s n a r r o w s a m p l i n g , o r i n n o v a t i o n s t u d y , w e c a n trace a lineage from Thomas Paine’s bridges for the Hudson and Schuylkill Rivers, to the unrealized deltaic innovations proposed by Juan Bautista Medici at the Mississippi, to the built works of Lewis M. Haupt. They are linked not only by their integration of known geographical locations with s p e c i fi c t e c h n o l o g i c a l i n n o v a t i o n , b u t a l s o t h r o u g hte precedent they establish for innovation in the environmental arts—work as relevant and formative today as it has been for centuries.

Given the contingency of landscape, it is shocking to see patents proposing environmental solutions to large geographies—deserts, rivers, coastlines—with no indication of place whatsoever, in either drawing or text. Richard Hindle’s account of patents without place offers a rare look—at once revealing and surprising—at the patent process in relation to landscape. Hindle does include examples where location is mentioned in the text or indicated on a map, but one catches on quickly that leaving place out supports a patent’s claim to universal applicability. Even more shocking is just that fact: that patents would deal with large geographies and propose environmental solutions. One imagines a patent to be an object that is a new invention, a machine of some kind, not a large- scale land management strategy formulated in singular circumstances. For readers not familiar with these patents and their s i g n i fi c a n c e f o r l a n d s c a p e , t w o f u r t h e r o b s e r v a t ions w a r r a n t c o n s i d e r a t i o n . T h e fi r s t i s t h a t i n v e n t i v e r e s p o nse to complex environmental problems with which we are wrestling today began appearing in patents two centuries ago. For example, James Buchannan Eads—the designer and builder of the Eads Bridge in St. Louis, among other important works—offered solutions for the management of the Mississippi River. A most creative engineer, Eads engaged in a long battle with civil engineer Andrew A. H u m p h r e y s a n d t h e U S A r m y C o r p s o f E n g i n e e r s ( U S A C E ) about the treatment of the Mississippi and proposed solutions more in line with present-day environmental understanding than the levees-only approach that the USACE adopted in winning that battle. Interesting alternatives are described in two of the patents illustrated by Hindle: Eads and James Andrews’s “Mattrass for Forming E m b a n k m e n t ” ( U . S . 1 7 0 , 8 3 2 ) a n d L i n u s B r o w n ’ s “ S y s t e m o f P r o t e c t i n g R i p a r i a n L a n d s f r o m O v e r fl o w ” ( U . S . 4 8 8 , 4 2 2 ). I n t h e l a t t e r o f t h o s e , M i s s i s s i p p i fl o o d w a t e r s a r e d e v i a ted to low-lying terrains and marshes, restoring them with the silt needed to maintain their ecosystems. This is closely related to Eads’ proposal of cutoffs in his long battle with Humphreys. The second observation is that landscape-based patents with a location are more convincing and understandable, at least to an engineer, environmentalist, or landscape architect, than are those without. But to those reading patent applications—not engineers with environmental training, one imagines—location could not have counted for much, at least then. The spread of environmental knowledge and public airing of the problems with past solutions make t h e t a s k o f t h e p a t e n t o f fi c e a m o r e i n f o r m e d o n e t o day. In the end, a question hangs in the air as to the validity of patents torn from the sites that elicited them. Contingency and place are central to landscape: “A landscape, like a m o m e n t , n e v e r h a p p e n s t w i c e . T h i s l a c k o f fi x i t y i s landscape’s asset.”27 W i t h t h a t i n m i n d , H i n d l e ’ s “ P a t e n t and Place” calls for a new look at patents—both old and new—proposing environmental solutions for large territories.
