Radical Patent Reform Is Not on the Way
[This paper is the first of a two-part series. The concluding article is "Reducing the Cost of IP Law"]
Hardly a day passes when we do not hear of one patent abuse or another. Ridiculous patents are issued or filed and companies are enjoined from selling their products. Judgments are issued, and settlements reached, for billions of dollars. (See the Appendix for examples of ridiculous patents and outrageous judgments.) Not surprisingly, there is a growing demand for reform of our patent system.
Whether their demands are modest or radical, the reformers share the belief that the patent system is broken; has gotten out of hand; and is not in sync with our fast-paced, high-tech, open-sourced, digitized world — in short, that it needs to be fixed.
At first glance, it might appear that change is already under way. In recent years the Supreme Court has issued a spate of decisions cutting back patent protection or making it more difficult to obtain patents. One of the most significant cases, KSR v. Teleflex, raised the "obviousness" bar. This raised the standards for getting a patent, and also made it easier to challenge the validity of issued patents.
In eBay v. MercExchange, the Court made it more difficult to get injunctions against the alleged infringer (alas, too late for poor BlackBerry). The MedImmune decision made it easier for licensees to challenge the validity of patents they had previously licensed. Microsoft v. AT&T restricted the global reach of US patent law.
And the Court of Appeals for the Federal Circuit (CAFC) — the sole appellate court for patent cases since its creation in 1982 — changed the standard for "willful infringement" in the Seagate case, making it harder to obtain enhanced (treble) damages. Most recently, in Quanta v. LG Electronics, decided in June 2008, the Supreme Court refined the "patent exhaustion" doctrine to make it more difficult for patentees to extract royalties from multiple parties for the same device or process.
The U.S. Patent & Trademark Office (PTO) has also entered the fray. In August 2007, the PTO released new rules for patent practice that limit how many times a patent application can be "renewed" and also limit the number of "claims" in a patent application (these rules were enjoined just before taking effect, due to a suit from British drug maker GlaxoSmithKline).
Finally, Congress has been considering various amendments to the Patent Act. Possible changes include switching from a "first-to-invent" to a "first-to-file" system, reducing damage awards, reducing forum shopping, and making it easier to challenge issued patents.
Plus Ça Change, Plus C'est La Même Chose
According to the organized patent bar and intellectual property (IP) advocates, these recent and proposed developments are "radical." In other words, they go too far.
Patent attorney John R. Harris, for example, ominously intones:
The U.S. has the best patent system in the world. What I'm afraid of is that they are about to throw the baby out with the bathwater.… The new rules are radical. The new legislation is radical. They will cause fewer patents to be issued.
But the truth is that none of the developments noted above are really that dramatic. Patent law is always evolving due to court decisions, new rules issued by the PTO, and new legislation from Congress. Consider this brief sample of notable events in the history of patent law:
Patent Law Development
13.7 billion years ago
God invents the universe. He does this without permission of anyone else. He doesn't look in the Celestial Patent Office filings first to make sure he is in the clear.
1.9 million years ago
Grog invents using fire to cook food. Arrgg sees this and imitates it. Soon, the practice spreads. Ditto with living in caves, using spears to kill animals, building "houses," and dressing in cured animal hides. Nobody sues anybody. No patent system has been invented yet.
Sovereigns grant exclusive rights (monopolies) as a way to raise money without having to raise taxes. Strangely, nobody gets a patent on the idea of granting monopolies.
US Constitution authorizes Congress to grant to "Authors and Inventors the exclusive Right to their respective Writings and Discoveries" "for limited Times" in order "To promote the Progress of Science and useful Arts."
First Patent Act.
Patent exhaustion doctrine clearly established in Adams v. Burke.
Henry v. A.B. Dick Co. confuses the exhaustion rule with the separate doctrine of "implied license."
1912 decision (above) overruled by Motion Picture Patents Co. v. Universal Film Manufacturing Co.
Popular Science Monthly claims that the Patent Office "has become a national disgrace" because of the backlog of unprocessed patent applications. This complaint is still being made in 2009.
United States v. Univis Lens Co. case harmonizes the exhaustion doctrine with the related law of contributory infringement.
Congress significantly revises patent law, changing various aspects of settled law, e.g., in the areas of misuse and contributory infringement; it also codifies the exhaustion rule of Univis.
Congress amends patent law to allow patents on plants.
Graham v. John Deere "clarifies" obviousness standards.
Patent Cooperation Treaty enters into force.
The Court of Appeals for the Federal Circuit (CAFC) is established and given exclusive appellate jurisdiction in patent cases. This leads to the unification of patent law and the strengthening of patents and patent protection.
CAFC in Mallinckrodt, Inc. v. Medipart, Inc. again conflates exhaustion and implied license doctrine as in the overruled 1912 case, A.B. Dick. Exhaustion doctrine to be modified yet again in 2008 Quanta Computer v. LG Electronics case (below).
CAFC's In re Donaldson decision requires the "means-plus-function" test used during patent litigation to be applied by the PTO during patent prosecution as well.
Patent law is amended pursuant to GATT: patent terms changed from seventeen years from the date of issue to twenty years from date of filing. The right to file "provisional" patent applications is established.
In Markman v. Westview Instruments, Supreme Court declares that patent claim interpretation is a matter of law, not a question of fact; this leads to the "Markman hearings."
35 USC 287(c) added to Patent Act to exempt certain surgical methods from patent liability.
The Intellectual Property and Communications Omnibus Reform Act of 1999 enacts "most significant changes" in U.S. Patent law since the 1952 Patent Act, according to PTO Commissioner Dickinson. Changes include early publication of pending-patent applications and a limited first inventor (prior user) defense for prior users of business methods.
Microsoft v. AT&T restricts the global reach of US patent law. KSR v. Teleflex tightens "obviousness" standards, raising the bar for obtaining a patent, and making it easier to challenge the validity of an existing patent.
CAFC in Seagate changes the standard for "willful infringement," making it more difficult to obtain enhanced (treble) damages.
PTO releases new rules for patent practice that limit how many times a patent application can be "renewed" and also limit the number of "claims" in a patent application.
In Quanta Computer v. LG Electronics, the Supreme Court arguably overturns Mallinckdrot (1992) and clarifies the exhaustion doctrine yet again — making it more difficult for patentees to extract royalties from multiple parties for the same device or method.
The CAFC in In re Bilski further modifies the patentability test for software or business-method patents, partially overruling State Street.
As can be seen, since the inception of modern US patent law in 1790, the field has been continually in flux. There is no reason to single out the last few years. Modern patent law has evolved for over two hundred years and will continue to do so. Indeed, frequent and arbitrary change in the law, and the uncertainty that this breeds, is common in state-run, legislation-dominated legal systems. The fact that state law changes is not new.
But though various details of the patent system continue to morph pursuant to political pressures and legal trends, the essential aspects of the patent system have not changed at all: The scope of what is patentable has not shrunk appreciably. The term is still about seventeen years. Patents are still enforceable by injunction. The groundless presumption of validity is alive and well.
Patent defendants who win usually pay their own legal fees, as before. Defending patent lawsuits continues to be incredibly expensive. Lobbying goes on as before. Companies continue to need to obtain patents if only for defensive purposes.
Obviousness and novelty remain the standards for patentability — and these standards are still vague, nonobjective, and subject to unpredictable interpretation by an inept and bureaucratic government agency, by state courts, and by technically inept juries. And the patent system is still widely believed to be legitimate and necessary even while it is widely derided as seriously flawed.
And so, for the foreseeable future, companies will continue to spend lots of money obtaining patents. And small businesses will still face the threat of patent-infringement lawsuits and court-ordered injunctions that could put them out of business. And these suits will continue to cost literally millions of dollars to defend. "Bad" patents will keep being granted, and various patentability standards will always be murky, arbitrary, and uncertain.
This is not to say that recent changes will not be felt at all. Patent attorneys, for example, can expect to see more business as a result of all this legal turmoil. (Why many of them are complaining about these developments is a mystery.)
But other than more money being spent on patent attorneys and a relatively small, probably temporary, shift in the balance of power between patentees and alleged infringers, the patent system has not radically changed. All of the problems noted above stem from the basic nature of the patent system. They will not recede by merely tinkering with details and leaving the essential features of the system intact.
Principle v. Pragmatism; Abolition v. Revision
What adjustments, then, should be made to our current patent laws? The answer to this question depends, in part, on one's basic approach to law. Most people with an opinion on IP policy — both pro and anti — have a utilitarian mindset. They favor or oppose various patent policies based on whether or not these policies produce more societal wealth, in the form of extra innovation worth more than the cost of the system.
Others favor or oppose patent rights on more principled or deontological (rights-based) grounds. Some of them, such as Ayn Rand, argue that patent rights are important property rights; others maintain that patents should be abolished precisely because they undercut property rights.
As for the latter position — yes, property rights are indeed undercut by patents. And even on utilitarian grounds, it could be argued that the patent system imposes an overall net cost on the economy, and should therefore be abolished or radically curtailed. It is apparent, however, that the patent system is very entrenched, as is the wealth-maximization approach to policy making.
Calls for abolition of the patent system — especially those coming from a principled, rights-based approach — are very unlikely to be adopted at the present time. In my forthcoming paper, therefore, I recommend certain changes to the patent system short of abolition, assuming a general "costs-and-benefits" approach.
Accordingly, to determine what adjustments ought to be made to the patent system (again, putting arguments for abolition on principled grounds to the side), we need a sufficiently clear understanding of the nature and extent of the costs imposed by the system, as well as its alleged benefits. With this in mind, the forthcoming paper suggests a laundry list of obvious changes that should be made to the patent system to reduce its costs with only minimal impact on its purported advantages. Stay tuned.
Appendix: Examples of Outrageous Patents and Judgments
Examples of (at least apparently) ridiculous patents and patent applications abound (more at PatentLawPractice):
- Amazon's "one-click" patent, asserted against rival Barnes & Noble;
- Cendant's assertion that Amazon violated Cendant's patent monopoly on recommending books to customers (since settled);
- The attempt of Dustin Stamper, Bush's Top Economist, to secure a patent regarding an application for a System And Method For Multi-State Tax Analysis, which claims "a method, comprising: creating one or more alternate entity structures based on a base entity structure, the base entity structure comprising one or more entities; determining a tax liability for each alternate entity structure and the base entity structure; and generating a result based on comparing each of the determined tax liabilities";
- Apple's patent application for digital Karaoke;
- the suit against Facebook by the holder of a patent for a "system for creating a community for users with common interests to interact in";
- the "absurdly broad patent [issued to Blackboard] for common uses of technology if that technology is employed in the context of education" (see also Patent Office Rejects Blackboard E-Learning Patent One Month After It Wins Lawsuit, Techdirt (Mar. 31, 2008);
- Compton's (now Encyclopedia Britannica's) patent that "broadly cover[s] any multimedia database allowing users to simultaneously search for text, graphics, and sounds — basic features found in virtually every multimedia product on the market";
- Carfax's patent on a "method for perusing selected vehicles having a clean title history";
- Acacia's patent for putting a unique transaction number on a receipt;
- Pat. No. 6,368,227, covering swinging sideways on a swing;
The Supreme Court, in the 1882 case Atlantic Works v. Brady, 107 US 192, itself lists examples of patents issued to "gadgets that obviously have had no place in the constitutional scheme of advancing scientific knowledge … the simplest of devices." These included
- a particular doorknob made of clay rather than metal or wood, where differently shaped doorknobs had previously been made of clay;
- making collars of parchment paper where linen paper and linen had previously been used;
- a method for preserving fish by freezing them in a container that operates in the same manner as an ice-cream freezer.
- rubber caps put on wood pencils to serve as erasers;
- inserting a piece of rubber in a slot in the end of a wood pencil to serve as an eraser;
- a stamp for impressing initials in the side of a plug of tobacco;
- a hose reel of large diameter so that water may flow through the hose while it is wound on the reel;
- putting rollers on a machine to make it movable;
- using flat cord instead of round cord for the loop at the end of suspenders;
- placing rubber hand grips on bicycle handlebars;
- an oval rather than cylindrical toilet paper roll, to facilitate tearing off strips.
Below are a few notable or recent examples of large, significant, troubling, or apparently outrageous injunctions, damages awards, and the like:
Qualcomm has been enjoined from importing chips that help conserve power in cell phones (discussion; latest developments).

Farmer David Reaps What He Has Sown: A Patent Suit, Patent Baristas (Feb. 13, 2008) Even though "the practice of saving seeds after a harvest to plant the next season is as old as farming itself," patents prevent farmers from saving patented seeds.
Apple, Starbucks Sued over Custom Music Gift Cards, AppleInsider (Feb. 20, 2008) A Utah couple sue Apple and Starbucks over their "'Song of the Day' promotion, which offers Starbucks customers a iTunes gift card for a complimentary, pre-selected song download." The suit is based on a patent on a "retail point of sale for online merchandising" which allows customers to buy a gift card from a brick-and-mortar store and then go home and redeem the card online.
Apple Sued Over Caller ID on the iPhone, Techdirt (Feb. 27, 2008). The patent is on "matching up the phone number of an incoming call with a local contact database to display who is calling."
The new 802.11n Wi-Fi standard (which promises to significantly increase Wi-Fi speed and range) is in jeopardy due to patent threats. See Bill Ray, Next Generation Wi-Fi Mired in Patent Fears, The Register (Sept. 21, 2007).
SanDisk Sues 25 Companies for Patent Infringement: "Suits have been filed against 25 companies by the SanDisk corporation this week, as the company looks to stop businesses from shipping products it alleges are infringing on its work. SanDisk has filed suits against everyone from MP3 player manufacturers to USB hard drive creators. The list of defendants is staggering, and MacWorld notes if Sandisk succeeds it could have repercussions outside of the courtroom.… The court … complaints could affect the prices and availability of products made by companies targeted in the suit if SanDisk wins and the companies are barred from importing products into the U.S."

The VoIP phone service Vonage may be put out of business by patents. Sprint recently won a patent case against Vonage in which $69.5 million was awarded in damages. Sprint had planned "to ask the court to permanently ban Vonage from using its patented technology," but the case was subsequently settled for $80 million. However, in a separate patent lawsuit between Verizon and Vonage, the jury found that Vonage had violated three Verizon patents, and awarded Verizon $58 million in damages plus ongoing royalties. Vonage claims it has developed workarounds for two of the patents. See Kim Hart, Sprint Wins Patent Case Against Vonage: Reston Firm Awarded $69.5 Million in Second Blow to Internet Phone Company, Washington Post (Sept. 26, 2007); Peter Svensson, Vonage Settles Patent Suit with Sprint, BusinessWeek (Oct. 8, 2007).

Kinsella, Revolutionary Television Design Killed by Patents (2007).
BlackBerry's manufacturer, RIM, was forced to cough up $612.5 million after NTP used patent law to threaten to shut RIM down.
Microsoft was on the receiving end of a $1.5 billion jury verdict for infringing an MP3 patent held by Alcatel-Lucent (which was recently overturned).
After Kodak sought more than $1 billion in damages from Sun Microsystems for patent infringement, Kodak finally settled for $92 million. (And according to one colleague, the verdict resulted "in the immediate shutdown of Kodak's entire instant photography division, with the immediate loss of 800 jobs. And, some say, the eventual failure of Polaroid due to lack of any real competition to keep them on their toes!")
In another recent case, Freedom Wireless obtained a $150 million damages award against Boston Communications Group, Inc., which at the time had revenues of only about $100 million. In this case, the judge also refused to stay the injunction issues against BCGI (and by extension, its customers) pending appeal.
Smith International was forced to pay Hughes Tool Company $204.8 million for infringement upon Hughes's patent for an "O-ring seal" rock bit, which led to Smith filing for chapter 11 bankruptcy protection (this was in 1986, when $200 million was considered a large patent verdict).
As of March 2003, the top 5 patent infringement damage awards ranged from $873 million (Polaroid v. Kodak, 1991) to $204.8 million (Hughes Tool v. Smith International, 1986). The top 5 patent settlements ranged from $1 billion to $300 million. Damage Awards and Settlements, IP Today (March 2003); see also Gregory Aharonian, Patent/Copyright Infringement Lawsuits/Licensing Awards. Sadly, a $200 million verdict seems normal nowadays. The recent $156 million patent-infringement verdict against AT&T, for example — which could possibly be trebled by the judge — now looks like small potatoes.
Other recent cases include a $1.67 billion patent infringement verdict in favor of Johnson & Johnson against Abbott; a $400 million settlement paid to Abbot, by Medtronic, regarding stent devices; and a $716 million settlement paid to Johnson & Johnson by Boston Scientific (cardiac stents again).
 A patent is a state-granted legal right in an "invention," such as a device or process that performs a "useful" function. It is obtained by filing a "patent application" with the US Patent and Trademark Office (USPTO). The patent gives the patentee the right to exclude, i.e., to prevent others from practicing the patented invention.

Other groups advocating reform or highlighting abuse include Free Software Foundation; Business Software Alliance; Foundation for a Free Information Infrastructure; Progress & Freedom Foundation; League for Programming Freedom; Electronic Frontier Foundation; Software Freedom Law Center; Coalition for Patent Fairness; End Software Patents; and the U.S. Chamber of Commerce.
Groups opposing significant change (in particular opposing the raising of the "obviousness" bar by the Supreme Court in KSR v. Teleflex, which made it harder to get a patent and easier to challenge an issued patent) include, not surprisingly (1, 2), legal and business interests such as the American Bar Association (ABA), the American Intellectual Property Law Association (AIPLA), the Federal Circuit Bar Association, the Franklin Pierce Law Center Intellectual Property Amicus Clinic, Intellectual Property Owners Association, Pharmaceutical Research and Manufacturers of America, the Manufacturing Alliance on Patent Policy (MAPP), and a descriptively-named group of "Practicing Patent Attorneys."
 Raising the bar for obtaining patents, while making them harder to obtain in the first place, may also make future patents more difficult to challenge, once they survive the more stringent examination requirements.

 The Eastern District of Texas, in particular, has been a popular choice for patent litigation due to its "rocket docket" and patentee-friendly juries. See What Does Forum Shopping In The Eastern District Of Texas Mean For Patent Reform?; Why Did Blackboard File in East Texas; Judge Blocks Dynamic Web Patent Troll's "Forum Shopping." The draft amendments would impose strong limitations on venue, which would hamper the ability of patent plaintiffs to sue in this district.

 Katheryn Hayes Tucker, GCs Draw Line in the Sand Over Changes to Patent Law, Daily Business Review (December 13, 2007). Harris goes so far as to raise the possibility of a patent-reform-caused depression: "If we're about to go into a recession and all of a sudden you kill innovation in the country, we might not have a recession. We might have a depression." How Harris knows we have "the best patent system" is not explained; it's commonly believed among patent attorneys, for example, that European Patent Office examiners are much better than ours.

 However, it is still possible to obtain patent injunctions. See, e.g., Transocean v. GlobalSantaFe (S. D. Tex. Dec. 27, 2006) (permanent injunction granted; leading to acquisition of defendant by plaintiff); and Tivo Inc. v. EchoStar Communications Corp. (S. D.

 The court here abandoned State Street's "useful, concrete, and tangible result" test for patentability and reaffirmed the "machine-or-transformation" test. Under this latter test, such a patent is valid only if (a) it is tied to a particular machine or apparatus, or (b) it transforms a particular article into a different state or thing. See "Appeals Court Smacks Down Software And Business Method Patents without Apparatus or Transformative Powers," Patent Baristas (October 31, 2008); In re Bilski: Patentable Process Must Either (1) be Tied to a Particular Machine or (2) Transform a Particular Article, Patently-O (October 30, 2008).
 See Kinsella, Legislation and the Discovery of Law in a Free Society (1995).
 Such a threat was the reason RIM, BlackBerry's maker, paid $600 million to NTP even though NTP's patents were being re-examined by the PTO: RIM couldn't risk even a short-lived injunction. See also Patent Office Rejects Blackboard E-Learning Patent One Month After It Wins Lawsuit, Techdirt (March 31, 2008). Even after the eBay case, injunctions are still granted, as noted in endnote 15, above; or patent holders find alternative means of blocking competitors, such as ITC actions.
 Other than Seagate, which reduces the value of the lucrative "patent opinions" patent practitioners are often hired to write. On the uncertainty engendered by legal turmoil, see Kinsella, Legislation and the Discovery of Law in a Free Society.
 The process by which the patent law ebbs and flows, and continually changes, provoking cries of doom and disaster from biased, special-interest chicken littles, calls to mind an analysis by Llewellyn H. Rockwell, Jr., in his book The Left, the Right, and the State (Auburn, Alabama: Mises Institute, 2008), pp. xiii-xiv (emphasis added):
What is the state? It is the group within society that claims for itself the exclusive right to rule everyone under a special set of laws that permit it to do to others what everyone else is rightly prohibited from doing, namely aggressing against person and property.
Why would any society permit such a gang to enjoy an unchallenged legal privilege? Here is where ideology comes into play. The reality of the state is that it is a looting and killing machine. So why do so many people cheer for its expansion? Indeed, why do we tolerate its existence at all?
The very idea of the state is so implausible on its face that the state must wear an ideological garb as means of compelling popular support. Ancient states had one or two: they would protect you from enemies and/or they were ordained by the gods.
To greater and lesser extents, all modern states still employ these rationales, but the democratic state in the developed world is more complex. It uses a huge range of ideological rationales — parsed out between left and right — that reflect social and cultural priorities of niche groups, even when many of these rationales are contradictory.
The left wants the state to distribute wealth, to bring about equality, to rein in businesses, to give workers a boost, to provide for the poor, to protect the environment.… The right, on the other hand, wants the state to punish evildoers, to boost the family, to subsidize upright ways of living, to create security against foreign enemies, to make the culture cohere, and to go to war to give ourselves a sense of national identity.…
So how are these competing interests resolved? They logroll and call it democracy. The left and right agree to let each other have their way, provided nothing is done to injure the interests of one or the other. The trick is to keep the balance. Who is in power is really about which way the log is rolling. And there you have the modern state in a nutshell.
Likewise, the vested interests moan and caterwaul at the slightest change, thus making sure that serious, radical change is not even considered. This way, they keep the basic system intact.
