Patent Oddities

One of the most interesting things I have learned about in the course of studying for the patent bar is the amount to which patents are abused. Today I will share with you two of the most rediculous.

The first is a method for exercising cats using a light source.
You may think its cute to watch your cat run and jump for the light but you are infringing on this person's patent. Click here for a gander at the pdf.

Here are the claims from the patent available from the U.S. Patent and Trademark Office.

Method of exercising a cat

What is claimed is:

1. A method of inducing aerobic exercise in an unrestrained cat comprising the steps of:

(a) directing an intense coherent beam of invisible light produced by a hand-held laser apparatus to produce a bright highly-focused pattern of light at the intersection of the beam and an opaque surface, said pattern being of visual interest to a cat; and

(b) selectively redirecting said beam out of the cat's immediate reach to induce said cat to run and chase said beam and pattern of light around an exercise area.

2. The method of claim 1 wherein said bright pattern of light is small in area relative to a paw of the cat.

3. The method of claim 1 wherein said beam remains invisible between said laser and said opaque surface until impinging on said opaque surface.

4. The method of claim 1 wherein step (b) includes sweeping said beam at an angular speed to cause said pattern to move along said opaque surface at a speed in the range of five to twenty-five feet per second.

Kevin T. Amiss and Martin H. Abbott patented this in 1993, which means we only have to wait 3 more years before we can begin legally exercising our cats.


Trolling Patents
The second is the amount that patents are trolled by people with no expertise but look to exploit the complex system where we provide ownership of ideas. Haliburton decided to fight back and patented the process for trolling patents. Check it out here. Thankfully, they have promised to only use their super powers for good.

The inventor and the assignee of this patent have no intention of applying the techniques described herein offensively but instead intend to use the patent defensively to discourage patent trolls and the like from extortionist practices.


Blogging and Disclosure
I have been scarred to post about my coolest science thoughts because it will either start a patent clock or cause me to get scooped, neither of which sound particularly good. Thus proving that in science as in marriage one usually has more to gain from keeping your mouth shut than opening it.

As I study for the upcoming patent bar, I am awed by the seriousness of it all. Though it was not my intention when I began this journey, at the end of next month people could begin coming to me with their hair-brained ideas and request that I patent them, for a reasonable fee. Sure, most patents don't bring money to your bank, but it is quite humbling to think about how easy it is to thoughtlessly destroy someones dreams by forgetting something in the patent application.

After much thought and consideration, I will leave discussions of my scientific ideas to lab notebooks and co-inventors and instead place the spotlight on other scientists who have done some really cool stuff.

Stay on the lookout for articles on exciting new work by Craig Venter and Steven Benner, two of my favorite scientists.

Still too many scientists...

Apparently, its been like this for quite a while. This letter from Jonathan Katz from 1999 points out that he has "known more people whose lives have been ruined by getting a Ph.D. in physics than by drugs".

Ouch...

Still, I wouldn't be pursuing this career if I didn't think I could beat the odds, come up with something so revolutionary that it will change the world and support a family on it. I have some secret and highly innovative ideas as well as a backup plan.

Knowing that there is a problem is the first step to a solution.

Patent Bar Incoming? To be continued...

In a new take on future career developments, I am looking into taking the U.S. Patent Registration Exam (USPRE). At a low $150.00, the 3 hour computer based exam from United States Patent and Trademark Office (Prometrics website) gives you the right to act as a Patent Agent, to provide counsel and submit patents.

The exam is "open book" and based on the Manual of Patent Examining Procedure (MPEP).

If you are interested in checking out what it looks like, past exams can be found here and here is the practice exam book that I am planning on picking up to study for it.

I have only slightly toyed around with the idea of going into patent law before this, and I doubt that it will change my longterm career direction. I am pretty set on developing new uses for microorganisms and I expect that it will help me out along the way.

Too Many Graduate Students; Not Enough Jobs

Today, I offer two articles. The first article is from Scientific American about the current state of the US science and engineering job market, while the second deals with an alternative model to PhD education being explored in China.

Does the U.S. produce too many scientists?
This story by a really eye opening article on how the US overproduces scientific PhD's for the job market and how this bizarre system is maintained through the recruitment of foreign students to fill the ranks.

What I got out of the article is that:
1) US K-12 still produces some of the best graduates in the world. There are some big gaping holes in the public education system that merit fixing, but we should acknowledge that it still produces some really good students.
2) Those students who want to make money don't go into science.
3) Those that do go on to graduate school in science join a grant funding system which supports lots of cheap labor in the form of graduate students and "temporary" postdocs. Then when they graduate with PhD's and want to start their own labs, they discover that there are way too many PhD's for the number of career jobs available.
4) One solution is to switch funding from temporary postdoc's to longterm staff scientist positions. Another is to cap the number of foreign graduate students who are admitted to study in the US and make the cap respective of the market.

I don't feel like I know enough to comment on policy, but I am already weighing options for PhD work and I haven't even started grad school.


Do scientists really need a PhD?
BGI, a Chinese genomics institute doesn't think. The suggested model would be to jump into a research project right out of college without the typical PhD educational experience. While I may be a bit biased, my three years of lab tech work seem to be very similar to what PhD student would go through, minus the required classes and grades. While I look forward to being the first PhD in my family, I truly doubt that the letters, by themselves, will make me a better scientist. I believe that it is the hard work, scientific problem solving and long discussions with colleagues are what make the scientist.

My Future at the University of Texas at Austin

Its official, I will be entering UT's Cell and Molecular Biology Graduate Program this Fall with the singular goal of getting a PhD in four to five years, instead of the five to seven which seems far too common these days. There is more than enough time to smell the roses after graduate school is done, my first priority is gaining the skills and developing some IP that will provide an upwardly mobile career for myself and material funds to provide for my family.

The graduate life begins by rotating in three to four labs. These rotations are 11-weeks long and give you a general sense of what its like to work in those labs. I am fairly certain which labs I want to work in after interviewing with the Professors during the recruiting event.

Hal Alper - Chemical Engineering

Hung-wen (Ben) Liu - Medicinal Chemistry

Jennifer Maynard - Chemical Engineering

In addition to graduating "early", I intend to acquire outside funding to establish myself as "fundable" and gain practice writing the grants which will be a staple of an academic career. So far, I have applied for the National Science Foundation Graduate Research Fellowship, and hope to hear back from them in a month or two. With Mr. Obama increasing the funds for those fellowships, it seems well worth the effort to apply for them every year that I am eligible. There is also the Hertz Foundation and probably many more that I haven't looked into yet.

Science Fiction Writing: Something that I have been toying with for years has been writing science fiction. SciFi works, such as Star Trek, Jurassic Park and Heinlein all helped shape my interest in doing the hard science work to make the impossible possible. It is also possible to have a conversation with the public about issues too difficult to discuss directly through the medium of books and movies. I foresee some very serious biological issues which will confound non-scientific morale educators and scientists alike to resolve. While I don't intend to solve these problems by writing, I think people can grapple with their feelings on human cloning easier by watching Bladerunner (or Southpark for that matter) than when they are watching Cable News.

I once heard that Michael Crichton wrote ER while in med school. While I don't claim to be his caliber of writer (yet), it has convinced me to keep my eyes and ears open and the fingers tapping on the keyboard.

Lonnie Ingram: Engineering E. Coli for Fuels and Chemicals @UT 2/24/2010

Two weeks ago, Lonnie Ingram came and gave a talk here and I had a chance to take some notes which I will share with all of you as well as some of my thoughts.

Introductions...
Most fuel in the US is produced domestically. However we still import lots of oil for fuel and coproducts (like solvents).

Biomass is used in three processes right now US Whiskey (from corn), Brazillian Rum (from sugar cane) and University of Florida's Tequilla process (from lignocellulose, hexose and pentose aka starchy stuff like switchgrass ).
Production from cellulose requires acid/base pretreatment which creates inhibitors to cellulases. Usually by dropping the starch in a tub of acid or blowing it up. Then you can mix it in with your bacteria or enzymes in the fermenter.

1. Engineering Organisms for increased yields: Zymononas mobilis
By mucking around with this organism they were able to reduce the net energy loss into CO2 making the fermentation process more efficient. Then they eliminated competing reactions and then used increasing biomass as a selection marker for better ethanol production in directed metabolic evolution.

2. Increasing ethanol tolerance, the more the bug can stand the better for production. I don't remember any publication work that he mentioned.

3. Since there are multiple sugars in starchy sources its important to get the most out of them and he talked about the sugar co-utilization of xylose and glucose, and how it can be improved with mutations to methylglyoxal synthase.

4. Deconstruction and inhibitors: by using cellulases they showed how to skip the expensive liquid solid separation and wash steps and just go pretreatment (see above)->fermentation-> purification (getting your liquor out of the gunk). Now they just need to have the bacteria operate at higher temperature and pressure to get the cost down. The three major compounds which are extracted from the starch and function as inhibitors were furfural from hemicellulose (which Quaker Oats produces from corn hulls for use as solvent or in resins), acetic acid and hydroxymethylfurfural.

The first thing they did was look for a furfurol reductase using mutant screening. They found that sulfur relieved some of the furfural inhibition. Eventually discovering CysIJ reductase and that furans inhibit growth by depleting the NADPH pool.

6. Fermentation for co-production:lactic acid is a co-product in fermentation. They worked with a company to produce it for use in poly-lactic acid (PLA) for the production of bioplastic. Pediococcos IdhL. There is a big need for the production of D and L lactic acid to blend for bioplastic production.

7. Succinate is a key building block (on the DOE top 10) and work done by Xueli Zhang looked at improving yields through flipping pathways around to produce succinate from CO2.

He lastly mentioned how to promote synergy in the way plants are setup taking the waste CO2 from the fermentation part of the plant and producing succinate in another, I would expect to see networks like these in the world future biorefineries.

First Gatorade and now cellulosic bioethanol. The University of Florida really knows how to do technology transfer! Its really great to see academics pushing new tech into the private sector. This makes me cautiously optimistic about the chances of taking some tech that I develop as a grad student or postdoc to the market through a startup. I don't have anything yet, but I definitely have some ideas up my sleeve. Mr. Ingram failed to mention his funding sources but the idea of industry working with academics sounds like a good alternative source of research funding from the NIH/NSF.

2010 A Year of Hard Decisions: How to pick the best choice for a graduate program.

Recruitment Weekends Rock!
This past month has been a bit of a whirlwind for me. From just finishing up my applications to getting invited to visit my top choices for school, its been very rewarding to say the least. I visited UT's Cell and Molecular Biology Program on Jan 28th and 29th. Working in the building where the recruitment events were located was a bonus, as I got to finish up an experiment I was working on during the downtime at the end of the day. The event started off with a mixer at a hotel downtown where the non-local recruits were staying. The next morning we listened to some talks, went to a gigantic poster session and had some interviews with Faculty. The evening was topped off by a formal dinner and "magic show" downtown at Esthers Follies.

They say that everything is bigger in Texas, and the CMB program has over 120+ faculty associated with the program and growing. This is some consolation because even after working, living and breathing research at UT for over seven years, I still met Professors that I have never seen or talked to before. It was a great victory lap feel for me because of my lack of success at getting in last year and my residual envy of the recruits who did.

The Rice Biochemistry and Cell Biology interview was just as great of an experience. First of all, they flew me in on Thursday Feb. 11th and out again on Feb 13th. I know I could have driven but we only have one car and it would have been troublesome. Upon arrival, not only did they put me up in a great hotel, but my suite-mate got snowed in leaving me alone in what had to be 800-1000 sq feet of posh hotel excellence. The next morning I found out that only five recruits made it that weekend. The other two got snowed in. This was a bit of a shocker for me as UT had at least fifty people in attendance. Granted that was for CMB, Biochemistry and Microbiology, but vast difference in scale reminded me of how exclusive the "Texas Ivy" remains. Rice has some truly gifted Faculty. I met with six for interviews and each one seemed like they would make wonderful advisers. To cap the wonderful day Prof. Jonathan Silberg took us out for some of the best Thai food I have eaten.

Those recruiting visits presented a glorious end to the application season.

Invitations to study
I have since received invitations from both programs. This is very exciting news as less than a year ago I was furtively coming up with alternative career paths in the event that I didn't get into graduate school this year. Now, I had the pick of the litter and the hardest part is figuring out which top-ranked research institution will provide the best location for both both of our careers.

How to decide?
1) For those with a "pseudo-two body problem", consultation is absolutely necessary. This doesn't mean convincing or arguing, but a frank and dispassionate discussion with all the information on the table. A conversation devoid of personal desires and only hoping to find the best solution together.
2) Prayer and Meditation help to put things in perspective. There are a few prayers from the Baha'i Writings that really capture what I want better than I ever could.
3) Just roll the dice. We can't see the future and just have to try to make the best choice with the information presented to us.
